Is there a way to get the color of a pixel or area of an NSView during
the drawRect method? I'll be tiling the view with a grid of random
colors but each tile is based on the colors around it. I'd prefer to
call something along the lines of:
NSColor *aColor = [myView colorAtPoint: somePoint];
Rather than creating and filling a potentially quite large array of
colors.
