Torstennator b9b4ca064f PixelPaint: BrushTool performance optimization ...

This patch optimizes how the Brush-Tool modifies the pixels. The new
logic generates a "reference brush" with the required size, falloff
and color only once and uses that for the rawing operations. If no
editing mask is used the reference brush is writen via a blit operation
to the content or mask image. This increases the drawing speed and
therefore also allows bigger brush sizes.
