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...
While there are some methods you can use to determine the current color of a point on screen, there is no guarantee that they will be meaningful in the middle of a drawRect call.

This array is probably going to be a lot smaller than you're imagining it to be, especially if you use C arrays of color values for storage (rather than NSArray[NSArray[NSColor]]).
