Merge 120916 - Avoid overread in RenderWidgetHostViewWin::OnPaint
GetRegionData may return 0 to indicate error. This call is used both to
calculate the required buffer size and to fill the buffer with region
data. In the first case, if not checked, a zero-length buffer may be
allocated. In the second case, the buffer content is undefined. In either
case, we should not depend on the buffer content.
BUG=110176
TEST=Long tail crasher in gfx::Rect::Rect, called from
RenderWidgetHostViewWin::OnPaint.
