Detailed Description

Extends MyPaintSurface with support for spectral ops and multiple bounding boxes.

This extends the regular MyPaintSurface with three new functions that support the use of spectral blending, for drawing dabs and getting color, and additionally supports using multiple invalidation rectangles when finalizing drawing operations.

The interface functions for MyPaintSurface can be called with instances of MyPaintSurface2 via the use of mypaint_surface2_to_surface (or just casting). Concrete implementations of MypaintSurface2 should support this.
