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 ..

/* sampling */
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.
