 3//
 4//  Code for making unit testing of graphics/UI easier. Generally you
 5//  will only want to look at the macros:
 6//    GTMAssertDrawingEqualToFile
 7//    GTMAssertViewRepEqualToFile
 8//  and the protocol GTMUnitTestCALayerDrawer. When using these routines
 9//  make sure you are using device colors and not calibrated/generic colors
10//  or else your test graphics WILL NOT match across devices/graphics cards.
