comctl32: Don't get the background colour in ANIMATE_PaintFrame as this can be called inside a critical section. 

This could therefore create a deadlock if the processing for 
WM_CTLCOLORSTATIC ends up sending certain messages to the animate control.

So move the retrieval of the background colour into the callers of 
ANIMATE_PaintFrame but outside of any critical section.
