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!

- remove some silly array copying code for nurb displist generation - converted dl->flag to use consistent defines for cyclic U/V

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.

void forward_diff_bezier(float q0, float q1, float q2, float q3, float *p, int it, int stride);
- 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

fixed spacing in the headers to get rid of some warnings and some other little minor spacing issues.
