Fix #34040: Moving Normal Node with enabled Cycles Material Preview crashes Issue was caused by couple of circumstances: - Normal Map node requires tesselated faces to compute tangent space - All temporary meshes needed for Cycles export were adding to G.main - Undo pushes would temporary set meshes tessfaces to NULL - Moving node will cause undo push and tree re-evaluate fr preview All this leads to threading conflict between preview render and undo system. Solved it in way that all temporary meshes are adding to that exact Main which was passed to Cycles via BlendData. This required couple of mechanic changes like adding extra parameter to *_add() functions and adding some *_ex() functions to make it possible RNA adds objects to Main passed to new() RNA function. This was tricky to pass Main to RNA function and IMO that's not so nice to pass main to function, so ended up with such decision: - Object.to_mesh() will add temp mesh to G.main - Added Main.meshes.new_from_object() which does the same as to_mesh, but adds temporary mesh to specified Main. So now all temporary meshes needed for preview render would be added to preview_main which does not conflict with undo pushes. Viewport render shall not be an issue because object sync happens from main thread in this case. It could be some issues with final render, but that's not so much likely to happen, so shall be fine. Thanks to Brecht for review!

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.

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.

Fix #34867: cycles viewport render did not respect viewport visibility for modifiers with text/curve/surface objects. This is because the code here did not yet support the distinction between generating the tesselated mesh at viewport/render resolution and generating a separate displist/derivedmesh for render that is not stored in the object but created and freed on the fly.

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.
