The original version assumes that each drawable pixmap should have a valid private pixmap pointer. But this is not true after we create this libglamor. As the DDX layer may create a pure software drawable pixmap which doesn't have a private pixmap pointer. Signed-off-by: Zhigang Gong <zhigang.gong@linux.intel.com>
