Rather than applying the modifier to the object data, it will create a new shape
with the deformed vertices in there. Only mesh at the moment, other object
types on the todo.
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:

Blended shape keys can now be displayed & edited in edit mode. This
is much like showing an armature modifier in edit mode, and shape keys
now are a applied as a virtual modifier (for mesh & lattice only, curve
doesn't fit in the stack well due to tilt).
The main thing missing still is being able to switch between the active
shape key in edit mode, that's more complicated.. but the weights of
other shapes can be edited while in edit mode.
One thing to be careful about is that this does automatic crazyspace
correction, which means that if you edit a shape key with a low value,
the actual vertices will be moved to correct for that and actually move
a (potentially much) longer distance.
Also includes some UI tweaks, mainly placing some buttons horizontally
since the vertical list was getting too long.
Internal change to not apply the shape keys to the Mesh vertex coordinates,
but rather use it as part of the derivedmesh/displist evaluation. This only
has one practical advantage right now, which is that you can now make a
linked duplicate and pin it's shape key to a different shape than the first
object.
Further, this makes shape keys correctly fit into the modifier stack design,
which will help implement some other features later. Also it means the mesh
vertex coordinates are now really the orco's.
The patch was by Wael El Oraiby, who did a great job on it.
Yay for Wael! Commit of patch #19242.
There's also some CCGSubSurf stuff mixed in with this, though it's
still not working right (fixed tons of bugs, just the main ones
for some reason are still there, despite their original causes
being fixed :-/).
* Replaced FACESEL_PAINT_TEST macro with paint_facesel_test. This removes one more thing from BKE_global, and it'll make it easier to localize.
* Fixed sculpt paint cursor sometimes not showing.
(though it's not completely feature-complete yet).
I ported over the remove doubles code from the
old bmesh branch for this, and split it into two
bmops, "Weld Verts" and "Remove Doubles".
Weld verts welds specific verts together, while remove
doubles finds doubles and welds them.
I also reverted the hotkey change I made earlier.
actually two modifier datamask optimizations that were never done.
* Don't use modifier data mask for disabled modifiers.
* Check if UV data is needed for particle system instead of always
requesting it.
Start of planned DerivedMesh refactoring. The mface
interfaces in DerivedMesh have been renamed to reflect
their new status as tesselated face interfaces (rather
then the primary ones, which are now stored in mpolys).
short review: mpolys store "primary" face data, while
mfaces store the tesselated form of the mesh (generally
as triangles). mpolys are defined by mloops, and each
mpoly defines a range of loops it "owns" in the main
mloop array.
I've also added basic read-only face iterators, which
are implemented for CDDM, ccgsubsurf, and the bmeditmesh
derivedmesh. Since faces are now variable-length things,
trying to implement the same interface as mfaces would not
have worked well (especially since faces are stored as
an mpoly + a range of mloops).
I figure first we can evaluate these simple read-only
face iterators, then decide if a) we like using iterators
in DerivedMesh, b) how much of it should use them, and c)
if we want write-capable iterators.
I plan to write official docs on this design after I get
it more stable; I'm committing now because there's a rather
lot of changes, and I might do a merge soon.

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
Realtime modifiers applied on mesh objects will be supported in
the game engine with the following limitations:
- Only real time modifiers are supported (basically all of them!)
- Virtual modifiers resulting from parenting are not supported:
armature, curve, lattice. You can still use these modifiers
(armature is really not recommended) but in non parent mode.
The BGE has it's own parenting capability for armature.
- Modifiers are computed on the host (using blender modifier
stack).
- Modifiers are statically evaluated: any possible time dependency
in the modifiers is not supported (don't know enough about
modifiers to be more specific).
- Modifiers are reevaluated if the underlying mesh is deformed
due to shape action or armature action. Beware that this is
very CPU intensive; modifiers should really be used for static
objects only.
- Physics is still based on the original mesh: if you have a
mirror modifier, the physic shape will be limited to one half
of the resulting object. Therefore, the modifiers should
preferably be used on graphic objects.
- Scripts have no access to the modified mesh.
- Modifiers that are based on objects interaction (boolean,..)
will not be dependent on the objects position in the GE.
What you see in the 3D view is what you get in the GE regardless
on the object position, velocity, etc.
Besides that, the feature is compatible with all the BGE features
that affect meshes: armature action, shape action, relace mesh,
VideoTexture, add object, dupligroup.
Known problems:
- This feature is a bit hacky: the BGE uses the derived mesh draw
functions to display the object. This drawing method is a
bit slow and is not 100% compatible with the BGE. There may
be some problems in multi-texture mode: the multi-texture
coordinates are not sent to the GPU.
Texface and GLSL on the other hand should be fully supported.
- Culling is still based on the extend of the original mesh.
If you have a modifer that extends the size of the mesh,
the object may disappear while still in the view frustrum.
- Derived mesh is not shared between replicas.
The derived mesh is allocated and computed for each object
with modifiers, regardless if they are static replicas.
- Display list are not created on objects with modifiers.
I should be able to fix the above problems before release.
However, the feature is already useful for game development.
Once you are ready to release the game, you can apply the modifiers
to get back display list support and mesh sharing capability.
MSVC, scons, Cmake, makefile updated.

+bvhtree cache (if the derived model doenst gets destroyed then the same BVHtree can be used)
this was needed to allow shrinkwrap constraint to be usable.
It has been ready for a long time.. but only got merged now, for 2.49.
[18429] Typo in IPO Actuator

- Weightpaint back (CTRL+TAB or menu)
Also weightpaint is sortof non-modal, allowing to use all existing
hotkeys while in paint mode. Only leftmouse is overridden.
- Made vpaint and wpaint entirely local, stored in scene (and saved!)
- Small bugfix (also in 2.48): on weightpaint mode, all armature objects
in 3d window were drawing as active poses. Now only the armature
deformer is.
Nice point for the UI agenda: are paint modes on ACTION mouse? Only then
you can combine it with SELECT mouse...
soc-2008-nicholasbishop branch.
Note: any old code with multires_test() or multires_level1_test() can
just be deleted, not needed by the multires modifier.
- remove Verse support. This will be brought back in The Future (probably jiri + me)
This means 5k lines less in blenkernel.
- fix two small errors for global cleanup, now compiles properly with FFMPEG enabled too.
Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.
From the anti-globalization department:
G.obedit terminated!
Wherever possible, use CTX_data_edit_object(C) to get this
now. It's stored in scene now, and the screen context has
it defined.
