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.
