2.5 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.

bugfix [#19525] Curve modifier moves mesh geometry first more of a request then a bug but shows up a strange limitation with curve deform modifier, The mesh bounding box would set the deform axis start/end to map the deformation of the curve to. This means it ignored offset in the object location and object data location (you could use a dummy vertex to trick it). Old files wont change, added an option (next to stretch), called 'Bounds Clamp', old files have this behavior but newly made curves have it disabled. Double checked this gives useful results with stretch on/off and negative axis.

Biiig commit! Thanks to 2-3 weeks of cvs freeze... Render: - New; support for dual CPU render (SDL thread) Currently only works with alternating scanlines, but gives excellent performance. For both normal render as unified implemented. Note the "mutex" locks on z-transp buffer render and imbuf loads. - This has been made possible by major cleanups in render code, especially getting rid of globals (example Tin Tr Tg Tb Ta for textures) or struct OSA or using Materials or Texture data to write to. - Made normal render fully 4x32 floats too, and removed all old optimizes with chars or shorts. - Made normal render and unified render use same code for sky and halo render, giving equal (and better) results for halo render. Old render now also uses PostProcess options (brightness, mul, gamma) - Added option ("FBuf") in F10 Output Panel, this keeps a 4x32 bits buffer after render. Using PostProcess menu you will note an immediate re- display of image too (32 bits RGBA) - Added "Hue" and "Saturation" sliders to PostProcess options - Render module is still not having a "nice" API, but amount of dependencies went down a lot. Next todo: remove abusive "previewrender" code. The last main global in Render (struct Render) now can be re-used for fully controlling a render, to allow multiple "instances" of render to open. - Renderwindow now displays a smal bar on top with the stats, and keeps the stats after render too. Including "spare" page support. Not only easier visible that way, but also to remove the awkward code that was drawing stats in the Info header (extreme slow on some ATIs too) - Cleaned up blendef.h and BKE_utildefines.h, these two had overlapping defines. - I might have forgotten stuff... and will write a nice doc on the architecture!

changing the number of subdivisions for nurbs curves. this way each edge/segment gets the same number of points matching the resolution value. before, a nurbs curve would have the same number of points no matter if it was cyclic or not. This will make slight changes to objects on an animated path, but only noticable if the path has a low resolution. bug [#11744] NurbCurve Radius incorrect - now dosnt show bad results with order 4 on non-cyclic curve.

Made Nurb->type only store the type rather then mixing the type with flags. moved CU_2D to Nurb->flag in do_versions This made simple type checks confusing to read. many... if( (nu->type & 7)==CU_BEZIER) replaced with ... if(nu->type == CU_BEZIER) made setting rna curve_2d clamp the Z values. still more RNA/UI changes to do.

2.5 Font object + editing back. Was quite some work due to a myriad of globals all over! Works nicely 100% local now. To enable a single textedit operator, I've added a new keymap entry KM_TEXTEDIT, which gives all keyboard events to the handler. Also had to add a new keymap-add function to force a keymap handler in beginning of region handlers. In future this can be used to prioritize handlers. Also: split off the arrow keys (frame change) to a separate region level handler. Can be set with default flag in regiontype->keymapflag ED_KEYMAP_FRAMES

Fix #29005: Bezier/Surface Datablock switching bug? This commit updates curve datablock to respect curve dimension flag when setting datablock for curve. Not ideal but this makes behavior quite expected, avoids big changes in curves core stuff which depends on object type and prevents restrictions on changing data datablock which works in general cases.

Curve Selection Tool Refactor: This commit refactors curve selection system to use certain curve selections functions that encapsulate setting of selection flags. New function to select adjacent control points was introduced too. Refactoring made it possible to simplify certain existing selection functions quite a bit. New functionality was delivered as well. Select more/less works now with NURBS as expected. Also two new curve selection functions were added: Select Every Nth and Select Random. See http://wiki.blender.org/index.php/BlenderDev/Curve_Selection_Tools for further information.

More armature goodies; The B-Bones! (where the B can be read as 'block' or 'bezier' or 'b-spline') - set option on/off in edit buttons, armature panel - scaling of B-bones only works in editmode, use ALT+S to make bones fatter or thinner. Also works for constrainted transform - In pose mode, you now have a buttons panel with per-bone settings too Here you can find the "segments" button, which allows bones to interpolate between previous/next bones, including roll. - Buttons to control interpolation ("In" and "Out" are disabled, doesn't work satisfying yet NOTE: this doesn't give deform yet! Main purpose for now is to test if this drawing method serves to animate/pose armatures well. Still need to review proper interpolation methods... maybe bezier is too limited.

float *make_orco_curve(struct Scene *scene, struct Object *ob);
- added make_orco_curf, even does keys! - removed {lattice,curve}_modifier functions - changed render code to use displist for curve rendering instead of making its own. required adding a bevelSplitFlag field to DispList. I also fixed the bevel face splitting which did not work correctly in many situations. - changed so all curve data creation happens in makeDispListCurveTypes, includes making bevel list and filling polys - changed render code to use displist for surface rendering - removed Curve.orco variable, built as needed now - removed stupid BLI_setScanFill* functions... why use a function argument when you can use a global and two functions! Why indeed. (this fixed crash when reloading a file with filled curves and toggling editmode) - bug fix, setting curve width!=1 disabled simple bevel for no apparent reason - cleaned up lots and lots of curve/displist code (fun example: "if(dl->type==DL_INDEX3 || dl->type==DL_INDEX3)"). Hmmm! - switched almost all lattice calls to go through lattice_deform_verts, only exception left is particles - added DBG_show_shared_render_faces function in render, just helps to visualize which verts are shared while testing (no user interface). - renamed some curve bevel buttons and rewrote tooltips to be more obvious - made CU_FAST work without dupfontbase hack Also by the way I wrote down some notes on how curve code works, nothing spiffy but it is at: http://wiki.blender.org/bin/view.pl/Blenderdev/CurveNotes

* Fix: Disabled radius tapering on 2d curves with filled front or back. It would be really cool to get this working solidly, but there are many potential problems with the triangle face creation across the flat surfaces, especially when there are holes inside the curves. Maybe this could be a fun project for someone better at this than I? :) Taper object curves still cause similar problems... * Made the curve radius affect the 'Nsize' curve normal drawing too, so you don't need a bevel to see the value.

- 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.

Shape Keys 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.
