AI 143249: am: CL 142820 am: CL 142818 Fixes #1735278. Deep hierarchies could generate stack overflow exception due to new local variables introduces in Cupcake. This change removes 4 ints from the dispatchDraw/drawChild code path to save a bit of stack on deep hierarchies. This is a stop-gap measure but that's all we can/should do for now.
