Brush Datablock: - Added a new Brush datablock, only used by image paint, but intended to be used in texture paint, vertex paint, weight paint and sculpt mode also. - Being a datablock, these brushes can be saved, appended and linked. They have a fake user by default, to make sure they are saved even if not selected. Image Painting: - Replaced the img module with C code in imagepaint.c - Airbrush is no longer a separate tool, but rather an option that can be used for soften, smear and clone also. - Blend modes mix, add, subtract, multiply, darken and lighten have been added, code taken directly from vertex paint. Note to project files maintainers: - The img module was removed from SCons and Makefiles, and this should be done in other build systems also. I'll wait to remove the module from cvs, to not break compilation.

ImagePaint Refactoring: - ImagePaint now uses ImBuf directly, and the rect blending functions were moved into the imbuf module. - The brush spacing, timing and sampling was abstracted into brush.c, for later reuse in other paint modes. Float ImagePaint support. Textured Brushes: - Only the first texture channel is used now. - Options for size and offset should be added, but need to find some space in the panel, or add a second one ..

struct ImBuf;
Changed vertexpaint and weightpaint to use the standard Brush struct, so they too work with the brush panel. Note: these modes are only using color/alpha/size from Brush, so there's more integration work todo yet.

2.5 Sculpt: * Added a new Paint type in scene DNA. This is now the base struct for Sculpt. * The Paint type contains a list of Brushes, you can add or remove these much like material and texture slots. * Modified the UI for the new Paint type, now shows the list of brushes active for this mode * Added a New Brush operator, shows in the UI as a list of brush tool types to add * Made the sculpt tool property UI smaller and not expanded, expectation is that we will have a number of preset brushes that will cover the basic sculpt brush types TODO: * Vertex paint, weight paint, texture paint need to be converted to this system next * Add brush presets to the default blend

Changes/cleanup for sculptdata and brushes. Summary: * Removed texfade, wasn't a very useful option (same result can be created with the falloff curve) * Removed CurveMapping from sculptdata, moved instead to Brush * Removed rake field from sculptdata, moved to Brush.flag * Moved Anchored flag from sculpt to Brush, same for direction field * Removed BrushData, replaced usages with the regular Brush type * Removed hardcoded brushes and brush_type from sculptdata, replaced with a pointer to the current Brush * Made sculpt tool type settable in Brush * Changed symmetry and axis lock fields to flags

/* brush curve */
Grease Pencil: Lock current frame option It is now possible to make Grease Pencil Layers to keep displaying and editing the current sketch-frame with this option. This allows to draw a frame which contains markings made for different times (i.e. a spacing/timing chart that you can keep adding to as you scrub to different points on the timeline). Use the clipboard/camera toggle (the one beside the visibility toggle) to enable. This should get an icon of its own at some point...

Texturepaint now supports all the imagepaint brush settings, with the exception of the clone tool. One level undo for image- and texturepaint, only storing those tiles that changed. Test to improve texturepaint performance using glTexSubImage2D, only enabled with 2^n sized textures and mipmapping off. Painting a 2048x2048 texture is then pretty smooth here, as long as the geometry is not too complex.

Basic pressure sensitivity support in imagepaint, for opacity, size, falloff and spacing. Click the button labeled "P" next to the sliders. Works best for opacity, other options can give poor quality strokes in some cases. Also performance needs to be improved. Remember, works only on X11 and Mac, no Windows support for tablets yet.
