e2944936ac Fix for weight painting errors, as reported by Bassam.
- Undo/Redo didn't work
- Crash on using weightpaint with Armature-modifier (instead of parent).

Note: checking if an object is being deformed cannot be simply done with
checking for a parent anymore... for this a call in modifier.c has been
added; modifiers_isDeformedByArmature(Object *). It even returns the
Armature object pointer.

a77e3482f2 Saturday morning first cup of coffee hack (yeah, its a late
morning)

 - fun for the whole family, boolean mesh modifier... doesn't work
   with layered modifiers yet (just uses base mesh), although may
   god have mercy on your soul if you want to run boolean on a
   subsurf anyway
 - added displistmesh_add_edges

This exposes a bug in boolean, apparently the output is somehow
random (hash on alloc'd pointer value perhaps) which is sortof
lame.

It also makes more apparent the desire for some level of control
over dep graph evaluation during editmode (at the moment dep
graph is reevaluated for a mesh object in editmode, but since
mesh changes are on editmesh other objects don't really see
any change, so it is a wasted recalc).

0192536102 - added iterator to edgehash
- updated decimator to make edges
2005-08-23 02:29:22 +00:00
931d0fc235 - switch modifiers_isDeformedByArmature to also include
virtual modifiers
2005-08-22 20:25:54 +00:00
3d7ed80ed4 - added modifiers_isDeformedByArmature function 2005-08-22 20:24:59 +00:00
dd7bcb94bf - sillyness... added drawMappedEdges for mesh
- revert to drawLooseEdges instead of general drawEdgesFlag
 - ditched TFace edge flags, done dynamically now which also
   means don't need to recalc surface on flag changes
 - added BLI_edgehash, guess what it does
2005-08-21 20:48:45 +00:00
7804860cf6 - added mesh_strip_loose_faces, works in conjunction with make_edges
to get rid of faces with MFace.v3==0
 - change all Mesh's to have ->medge now. This is forced by make_edges
   on readfile, and in the various exotic important routines, and on
   conversion back in python.
 - make python NMesh structure always have medges now (needs testing)
 - with above two changes it is guarenteed that mf->v3 is never ==0
   in main blender code (i.e., all MFace's are actually triangles
   or quads) and so I went through and removed all the historic tests
   to deal with MFace.v3==0. Equals lots of deleting, I am in heaven!
 - removed MEdge edcode flag, no longer needed
 - added experimental replacement for edge flag system

Still are some inconsistencies in FACESELECT mode edge drawing to
be ironed out.

NOTE: This commit adds an experimental edge flag calc system, based
on 10-seconds-of-thought algorithm by yours truly. Would appreciate
feedback on how this system works, esp compared to old one and esp
on complex or interesting models.

To Use: New system is enabled by setting G.rt to a value between
1 and 1000 (Value of 0 uses old system). Value 1000 is reserved for
"auto" edge, which is more or less identical to old system but also
makes sure that at least 10% of edges are drawn (solves errors for
super subdivided meshes). Values between 1 and 999 act as percent
(out of 1000) of edges that should be drawn, starting with "most
interesting" edges first. Please try it and comment!

fff5d816ab - bug fix, mirror modifier could duplicate edges on boundary in
certain cases
2005-08-20 20:04:32 +00:00
6c001485fa - bug fix for stooooopid crash in mirror modifier 2005-08-20 18:25:11 +00:00
a30740c196 - convert all DerivedMesh map functions to use index based
mapping (instead of Edit{Vert,Edge,Face} pointers)
 - dropped convertToDispListMeshMapped (whew, glad of it too)
 - added DerivedMesh drawMappedFaces function
 - dropped EM suffix for DerivedMesh functions, it was neither
   particularly correct nor descriptive
 - converted test_index_mface to test_index_face that also corrects
   MCol and TFace. Good thing we had three versions of this routine,
   you never know when one might burn down.
 - removed flipnorm_mesh, not used anymore (and was incorrect to
   boot)

 - Getting face select to work with modifiers turned out to be much
   more complicated than expected. Reworked mapping architecture for
   modifiers - basically elements in a DispListMesh are now required
   to be stored in an order that corresponds exactly to original
   ordering. MVert/MEdge/MFace all have a new flag ME_XXX_STEPINDEX
   that is set on each element that is set on the first derived element
   of each original element. I can't say the code to follow these
   requirements for subsurf is particularly transparent, but on the
   upside it is a reasonably consistent and simple system that is memory
   efficient and allows keeping the DispListMesh structure.

 - rewrote mirror modifier to be simpler/conform to new requirements
   for mapped DispListMesh structure. This also means that mirror interacts
   much better with incremental subsurf calculation (it used to recalc
   one entire side on any topology change, now it generally avoids that).

 - added EM_{init,free}_index_arrays and EM_get_{vert,edge,face}_for_index
   functions to handle mapping indices back into appropriate EditMesh
   structures.
 - bug fix, make edges didn't recalc object data
 - bug fix, initial image assignment to TFace's didn't recalc object data

 - new feature, added circle select support for FACESELECT
 - bug fix, creating new faces in editmode duplicated the TFACE active
   flag - but there should only be one active tface
 - bug fix, possible crash when deleting all faces in faceselect mode
   on mesh with tfaces...

Still todo: TFace edge drawing is still not always correct in face
mode, in particular with a mirror modifier when mesh has edges (and
no preceeding subsurf). Have not yet decided how to deal with this.
Best solution is probably to do switch to meshes all having MEdge's,
in which case I can get rid of TFace edge flags (and need to recalc
modifiers on tface selection change).

43e329edb7 softbody <--> softbody collision
make softbodies collide with objects patented to armatures (bones), lattices .. )

Softbody deflectors always use the new modifier stack. (thanks ZR)

Softbody deflector code checks for identity of colliding objects so,
there is no need to prohibit softbodies to be a deflector.

So now you can put some soft balls in a box and see them bounce.

1dcec68ab4 EditMode armature: mirrored editing feature.
- Option is in EditButtons, Armature panel.
- Currently only local X-axis mirror (seems to be default anyway)
- Transform then applies changes to the mirrored-name bone as well.
- Extrude: also does the counterpart Bone
- New: SHIFT+E extrude: extrudes 2 mirrored Bones out of a normal Bone.
  (creating names by appening _L and _R)

Or in short: you can now model a full rig without any manual naming!
Of course the names are not too nice... a couple of ideas to explore;
- rename a mirrored bone renames counterpart too
- allow in weightpaint mode to select Bones
- and of course mirrored edit in PoseMode (if that's useful...)

Important note: I tweaked the naming convention a bit; names like
Bone_L.005 and Bone_R.005 are considered counterparts. However, if
you use the "Flip names" option, the number extension is still
truncated.

BTW: Commits in Zr's code are fixes for gcc warnings. :)

2abd79b491 - readded DL_VERTS type to store lattice deformed verts
- new feature, twiddled with lattice resizing to try to maintain
   existing vertex changes... much nicer than just resetting the
   lattice if you decide you need more detail in the lattice.
 - modifiers work with lattices now. yes, that does mean you
   can make a chain of lattices effecting each other 8 miles
   long.
 - some cleanup of softbody code, was rather splintered and call
   path was twisted and confusing. reworked main object step
   routine to do things in a more obvious and consistent manner
   and without duplicate code
 - added ob->softflag OB_SB_RESET instead of sbObjectReset
   call
 - modifier changes reset softbody now
 - moved curve_getVertexCos/curve_applyVertexCos into curve.c
 - update curve modifier eval to work with virtual modifiers
 - update modifier apply to work with curves/surfs
 - update make parent to also recalc object data

NOTE: Although you can turn SB on for curve/font objects at the
moment it doesn't really work because they call deform in
multiple steps and this confuses SB. Not sure how to deal with
atm.

74623f33aa - get rid of unused object_deform_curve
- some tweaks to modifier UI thanks to Bart (aligning buttons)
2005-08-15 00:53:51 +00:00
5c74f25c8a Two quick bugfixes, thanks slikdigit!
- armature modifier was not flagged to require original data (but it
   does)
 - add hook messed up the ModifierData initialization, stupid bug!
2005-08-11 05:45:47 +00:00
75bcb4cd98 - added modifiers_getVirtualModifierList, returns pointer to first modifier
but including "virtual" modifiers (for example, an object skel-parented
   to a lattice has a virtual first lattice modifier)
 - removed mesh_modifier(), all functionality has been incorporated into
   modifier stack (well, keys still don't exist as a modifier, but I am
   not sure if they should).
 - added interface option to convert a virtual modifier into a real modifier
 - added option to parent to lattice object or lattice with deform
 - bug fix, patch of hook indices patched all hooks (oops) not just ones
   for edited mesh

NOTE: Files saved with 2.38 that include an object parented to a lattice
will not load correctly, because it will look like the object is parented
only to the object (i.e. without deform). Can be simply fixed by reparenting
or adding a lattice modifier. Older files are handled automatically.
2005-08-11 03:31:33 +00:00
ac3ed0f92a - switch to using softbody modifier, controls enabling but does not have
variables, these are still in same place. enable button automatically
   makes/enables modifier.
 - changed hook to hook modifier conversion to happen on direct link,
   required to make sure we don't forget to free any memory for files
   saved with 2.38 that have hooks.
 - update modifier interface to enforce modifiers with the require-original-
   data flag to not move beyond deforming modifiers.
 - enforce only one softbody modifier allowed

NOTE: Once again, no modifier stack for lattice yet means softbody for
lattice does not work atm.
2005-08-11 02:23:52 +00:00
2b40f19c5b - bug fix, hook deform could crash because old files can have hook
indices that are out of range
 - bug fix, hook indicies were not corrected on exit editmode (there
   probably should be a general interface for this kind of patch)
2005-08-10 22:25:32 +00:00
9030e5f686 - added eModifierTypeFlag_RequiresOriginalData for modifiers that
can only follow deform (for example, they store mesh vertex
   indices)
 - added ModifierType.foreachObjectLink for iterating over Object
   links inside modifier data (used for file load, relinking, etc)
 - switched various modifiers_ functions to take object argument
   instead of ListBase
 - added user editable name field to modifiers
 - bug fix, duplicate and make single user didn't relink object
   pointers in modifier data
 - added modifiers to outliner, needs icon
 - added armature, hook, and softbody modifiers (softbody doesn't
   do anything atm). added conversion of old hooks to modifiers.

NOTE-THE-FIRST: User name field is not initialized on loading 2.38 files
so if you have saved stuff with a cvs blender you will see blank names.

NOTE-THE-SECOND: Since modifiers aren't evaluated yet for non-Mesh
objects, hooks for lattices and curves are broken. Don't updated if
you actually, say, *use* Blender.

NOTE-THE-THIRD: Old hooks used a quirky weighting system during
deformation which can't be extended to modifiers. On the upside,
I doubt anyone relied on the old quirky system and the new system
makes much more sense. (Although the way falloff works is still
quite stupid I think).

1f431b50d6 - got rid of DerivedMesh.drawMappedEdgeEM function, can be implemented with
drawMappedEdges
 - added DerivedMesh.convertToDispListMeshMapped function which converts and
   also returns mapping information for use in editmode
 - updated DispListMesh derivedmesh to be able to function in editmode
 - update mirror modifier to support use as a cage
 - update mirror & subsurf modifiers to properly pass mapping information down
   modifier stack

It is now possible to have a mesh with mirror/subsurf modifiers where you
can edit with both as cage. Selecting the mirror'd part works, but of course
transform is flipped so it is a bit weird. Not the cleanest code in the
world and I can't say I am really happy with the architecture but it works for
now and supports the existing feature set.
2005-08-07 05:42:03 +00:00
8da5df8887 - add allowShared argument to DerivedMesh.convertToDispListMesh to allow returned
DLM to share data from DerivedMesh (reduces some copying/memory allocation)
 - added displistmesh_copyShared function to copy a DLM but not duplicate any
   internal data
 - changed crease drawing to use DerivedMesh functions... this means varying
   edge width style of creases had to go, I replaced by using varying color to
   show crease weight instead. Don't think this is a big loss since the subsurf
   result gives you a much better indication of the crease weight anyway.
 - bug fix in mirror modifier, didn't copy edge creases from editmesh correctly
2005-08-07 02:30:29 +00:00
8319b3d1fa - modifier UI update (aka, find the modifier buttons!!)
- moved back to editing buttons, where life is now cramped... switched
   to constraint style foldout panes, still a WIP. In particular not
   sure what buttons should be in header (and if current toggles stay
   in header if they should also be in an expanded pane). Also need
   new icons for move up/move down (and drag and drop would of course
   be nice). Finally current plane is to make it so modifiers will
   expand out in modifier pane for horizontal orientations instead of
   just going down down down to goblin town.
 - added error field to modifiers that is displayed in UI, need to have
   some way for modifiers to return errors back to interface (esp. important
   for python)
 - tweaked cage determination and handling, currently the editmode cage
   is determined by last modifier with OnCage set that is preceeded completely
   by modifiers that support mapping or are disabled in editmode. it is
   kinda confusing, but the interface only lets you toggle OnCage for modifiers
   that support it - it just might not be clear all the time why you can't
   toggle a certain modifier OnCage.
 - update displistmesh_copy to only copy edges if non-NULL

There is a display bug that already existed but is more obvious with
new modifiers where parts of the pane get drawn in a different area
after toggling editmode. It has to do with drawing parts of the interface
using GL instead of 100% buttons. I try to keep my grubby little toes
out of the interface code so this can wait for Ton to return.
2005-08-04 07:25:43 +00:00
74820841df - removed BLO_findstruct_offset (obsolete)
- remove python access to Optimal and Subsurf flags (they don't
   work this way anymore, I suppose need to replace with python
   access to modifiers but not going to do right now).
 - removed interface access to OPTIMAL mode, needs to be rethough...
   this means at the moment subsurfs outside editmode always draw
   and render all edges
2005-08-03 19:56:27 +00:00
1db88bd065 - modify CCG to not crash when passed invalid faces, just ignores
that face... this situation should still not happen with well
   written modifiers but at least it won't crash now
 - bug fix in mirror modifier, calculation during editmode did not
   check to make sure built mface's had valid indices... grr the
   ==0 tagging system is really a pain.
 - convert a few uiDefBut calls to use explicit type
2005-08-03 19:27:19 +00:00
8a58197cf3 - change modifier applyModifier[EM] function to not free derived argument
- added modifier_supportsMapping function
 - update CCG to set actual vertex normal (and not just
   interior face vertex normal, bla bla bla no one knows
   what this means nevermind).
 - renamed modifierType_get_info to modifierType_getInfo for
   consistency and to increase my commit line count.
 - update EditMeshDerivedMesh to calculate (and use new) normals
   when given deformed vertices
 - added
 - update editmode modifier calculation to also calculate a cage,
   not working 100% atm, in particular if a deformer follows a modifier
   that returns a DerivedMesh the cage is not accurate.
 - added ccg derivedmesh drawMapped{Vert,Face]NormalsEM functions
 - currently UI for selecting the cage mesh is rather irritating,
   will be updated
2005-08-03 04:04:05 +00:00
4b1588e277 - update storage.c to use standard time codes (should fix issue
with MSVS 8)
 - broke mesh_create_shadedColors out of shadeDispList, used to
   build vertex colors for mesh in vpaint as well (also fixed
   bug where they were not initialized correctly for subsurfs)
 - added modifier_copyData and modifier_findByType functions
 - change editmode modifiers to only calculate if Realtime and
   Editmode bits are both set, makes more sense for copying
   modifiers
 - update object_copy to correctly copy modifiers
 - removed duplicate redefinition of ME_ attributes in python,
   this is a horrible idea, why was it done in the first place?
 - update armature auto vertex group code to check for subsurf
   in modifier stack
 - fixed flip_subdivision to work with move to modifier stack
 - added copymenu_modifiers, can copy all modifiers or just
   data from first modifier of a certain type (not sure how
   to deal with multiple modifiers of same type... not
   a big issue though I think)
2005-07-27 20:16:41 +00:00
c25b7117d0 - decimator modifier was giving wrong # of verts when a previous
modifier was active
2005-07-26 23:38:26 +00:00
2c20d7529a - bugfix, mirror modifier didn't copy deformed vertex cos for shared
verts
2005-07-26 06:39:58 +00:00
951a4934b0 - added wave modifier & removed old wave effect
- added decimate modifier & removed old decimate interface
   (currently lacks warning about destroying data, and there needs
   to be a way for modifiers to return errors back to the interface)
 - allow applyModifier to return NULL to indicate error
 - unfortunately new decimate modifier means it does not know exact
   number of faces in mesh (other modifiers may come before) and so
   instead interface uses a percentage. if people need exact face
   count slider then I will have to think of some hack to fit this
   in. note that it does display the output face count so its possible
   to tweak the pct to get what you want regardless.
 - removed python Wave object

If you are bored now how much easier it is to implement something
like decimate as a modifier. Very few changes to interface, very
few entry points.
2005-07-26 02:44:59 +00:00
0a6ca24661 - warning fixes
- rare bug in calc_vertexnormals, fourth vertex normal was not flipped
   correctly (found thanks to my new auto regression test script)
2005-07-24 19:13:27 +00:00
e331e68b57 - added ModifierData flag, is modifier enabled in editmode
- added modifier type flag: should modifier be enabled by default for
   active in editmode
 - added subsurf "debug incremental" option instead of G.rt==52 (it becomes
   a slightly useful feature now for debugging how well a modifier works
   with incremental subsurf... maybe important for future python modifier
   developers)
 - shuffled modifier button layout just to keep people guessing
 - switched back to drawing editmesh face centers not through derivedmesh,
   I didn't think this one through, forgot that centers were also used for
   selection. have to think about what to do about this, should be either
   (a) don't draw centers with a cage active (optimal mode) or (b) come up
   with api to draw centers through derivedmesh and also handle selection.
 - changed recalc_editnormals to also follow the len(no)==0.0 use vertex
   co convention
2005-07-23 19:15:08 +00:00
e125ed5958 - fix a bug with softbody, verts were copied out of order (meant
history was lost... I think, dunno this code well.)
 - commented out code to do merging of quad with 3 verts shared in
   mirror mode... didnt seem worth the effort and mesh still wasnt
   perfect afterwards
 - bug fix, indices for triangles were not swapped correctly in
   mirror, could lead to crash with subsurf in editmode
2005-07-23 06:05:29 +00:00
e546e81762 - added data arguments to deformer modifiers, in case someone wants
to write one that is based on geometry (and not just vertex position)
 - added editmode versions of modifier deform/apply calls and flag
   to tag modifiers that support editmode
 - added isFinalCalc param to applyModifier, basically a switch to let
   subsurf know if it is calc'ng orco or not (so it can deal with cache
   appropriately). This is kinda hacky and perhaps I can come up with
   a better solution (its also a waste to do a complete subdivide just
   to get vertex locations).
 - changed ccgsubsurf to not preallocate hash's to be approximately correct
   size... this was probably not a big performance savings but means that
   the order of faces returned by the iterator can vary after the first
   call, this messes up orco calculation so dropped for time being.
 - minor bug fix, meshes with only key didn't get vertex normals correctly
   calc'd
 - updated editmesh derivedmesh to support auxiliary locations
 - changed mesh_calc_modifiers to alloc deformVerts on demand
 - added editmesh_calc_modifiers for calculating editmesh cage and final
   derivedmesh's
 - bug fix, update shadedisplist to always calc colors (even if totvert==0)
 - changed load_editMesh and make_edge to build me->medge even if totedge==0
   (incremental subsurf checks this)

todo: add drawFacesTex for ccgderivedmesh

So, modifiers in editmode are back (which means auto-mirror
in edit mode works now) although still not finished. Currently
no cage is computed, the cage is always the base mesh (in
other words, Optimal edge style editing is off), and the final
mesh currently includes all modifiers that work in edit mode
(including lattice and curve). At some point there will be toggles
for which modifiers affect the final/cage editmode derivedmesh's.

Also, very nice new feature is that incremental subsurf in object
mode returns a ccgderivedmesh object instead of copying to a new
displistmesh. This can make a *huge* speed difference, and is very
nice for working with deformed armatures (esp. with only small
per frame changes).
2005-07-22 07:37:15 +00:00
24f2b61fdb - add comments to BKE_DerivedMesh.h about which functions are called in editmode
- gcc warning fixes
 - start work to make CCGDerivedMesh able to run in object mode (hint: more
   speed improvements)
 - fix modifier move down tooltip
2005-07-21 21:19:38 +00:00
33709bf6e2 - shuffled editmesh derived function name/function
- added ModifierTypeInfo.freeData function
 - added modifier_{new,free] utility function
 - added ccgSubSurf_getUseAgeCounts to query info
 - removed subsurf modifier faking (ME_SUBSURF flag is no
   longer valid). subsurf modifier gets converted on file load
   although there is obscure linked mesh situation where this
   can go wrong, will fix shortly. this also means that some
   places in the code that test/copy subsurf settings are broken
   for the time being.
 - shuffled modifier calculation to be simpler. note that
   all modifiers are currently disabled in editmode (including
   subsurf). don't worry, will return shortly.
 - bug fix, build modifier didn't randomize meshes with only verts
 - cleaned up subsurf_ccg and adapted for future editmode modifier
   work
 - added editmesh.derived{Cage,Final}, not used yet
 - added SubsurfModifierData.{mCache,emCache}, will be used to cache
   subsurf instead of caching in derivedmesh itself
 - removed old subsurf buttons
 - added do_modifiers_buttons to handle modifier events
 - removed count_object counting of modifier (subsurfed) objects...
   this would be nice to add back at some point but requires care.
   probably requires rewrite of counting system.

New feature: Incremental Subsurf in Object Mode

The previous release introduce incremental subsurf calculation during
editmode but it was not turned on during object mode. In general it
does not make sense to have it always enabled during object mode because
it requires caching a fair amount of information about the mesh which
is a waste of memory unless the mesh is often recalculated.

However, for mesh's that have subsurfed armatures for example, or that
have other modifiers so that the mesh is essentially changing on every
frame, it makes a lot of sense to keep the subsurf'd object around and
that is what the new incremental subsurf modifier toggle is for. The
intent is that the user will enable this option for (a) a mesh that is
currently under active editing or (b) a mesh that is heavily updated
in the scene, such as a character.

I will try to write more about this feature for release, because it
has advantages and disadvantages that are not immediately obvious (the
first user reaction will be to turn it on for ever object, which is
probably not correct).
2005-07-21 20:30:33 +00:00
dc232fda47 Wow! A new feature!
- made ModifierData.isDisabled optional
 - Added new modifier type: Mirror
    o modifier system isn't running in editmode yet so still
      don't have mirrored editing, but otherwise it is pretty
      cool. code even goes to tricks to make sure mirror join
      looks nice in degenerate cases.
    o this kind of commit is basically the upshot of all the
      previous commits - in that implementing a new modifier
      changes only about 3 files and still integrates nearly
      completely.
2005-07-20 07:11:26 +00:00
eb9d466b48 - orco fix for build effect, didn't copy input vertex cos over (duh!) 2005-07-20 04:56:15 +00:00
38e0d79e68 - for some reason mesh_create_derived_no_deform took the raw data (not
an object) but this is not going to work... I can't remember the reason
   I did it this way in the first place either! oops! regardless, switch
   to all mesh_ derived accessors taking object argument. there is still
   a bug in render orco calculation though. (hunt hunt)
 - removed python files that should have been ditched in previous commit
2005-07-20 04:44:02 +00:00
259c7b6cad - added modifier_dependsOnTime to check if modifier needs updating
based on time change. would be nice if dep graph could handle this.
 - made dep check if modifiers need update on time change
 - fix render crash (access null)
 - added new Build Effect modifier type. compared to old one works as
   a full member of modifier system, means can apply subsurf, etc on
   it, reorder, what have you. and it is all nice and self contained.
 - removed old Build effect, old files convert to new style on load
 - couldn't help myself, added a randomize feature to build effect
 - removed Python BuildEffect support

d18600520e - added ModifierTypeInfo.updateDepgraph function, responsible for building
appropriate relations in dep graph (modifiers respond to scene changes
   correctly now)
 - update modifier buttons to trigger depgraph rebuild if needed

1df154d140 - split {curve,lattice,armature}_deform_verts out of mesh_deform
- removed mesh_deform (merge into mesh_modifier)
 - switch python lattice_apply function to use object_apply_deform,
   this isn't exactly equivalent but the python system shouldn't
   have been calling that deep into the kernel anyway.

New feature: Modifier stack
 - added Object.modifiers (list of ModifierData elements)
 - added DNA_modifier_types.h
     o contains type definition for the file data for the various
       modifier types
 - added BKE_modifier.h
     o contains modifierType_get_info (access to modifier type registry)
     o structs and defines for runtime modifier usage
 - updated mesh_calc_modifiers to evaluate modifier stack (note that
   for the time being it also evaluates the old style modifiers so files
   should load and work as normal).
 - add file handling modifier code (todo: don't replicate on object copy)
 - add modifier stack UI code (lives in object panel)


Only real new feature at the moment is that you can apply lattices and
curves *after* a subdivision surface which was never possible before.

Todo:
 - DEP graph updating does not work correctly yet, so you generally have
   to tab cycle to see results.
 - editmode calculation does not use modifier stack.
 - bug fixes (there must be a few in there somewhere)
