Fix one case where default Non-client painting can occur... before a window is fully activated, WM_NCPAINT can be called and if we do not suppress default handling in that case then Windows will attempt to draw the standard border/controls resulting in an intermittent flicker.
Fix one case where default Non-client painting can occur... before a window is fully activated, WM_NCPAINT can be called and if we do not suppress default handling in that case then Windows will attempt to draw the standard border/controls resulting in an intermittent flicker.

BUG=none
TEST=alt+tab quickly to and from Chrome in custom frame mode (Vista basic). Should be no non-client window flicker.
