Fixes a bug in CursorWithMask class>>#derivedFrom: that let
primitiveBeCursor fail because of an offset less than -16 at -16.
Try "(CursorWithMask derivedFrom: Cursor corner)
	showWhile: [Sensor waitButton]" (failes without this fix).
Also, makes the generated cursor prettier by centering it on it's mask.
Also, adds some utility methods (hasMask, withMask, etc.)
