[Intel-gfx] [PATCH 3/4] uxa/glamor: Let glamor do the GC validation.

[zhigang.gong at linux.intel.com]

From: Zhigang Gong <zhigang.gong at linux.intel.com>

If we are using GLAMOR, then a tile pixmap or stipple pixmap
may be pure glamor pixmap and thus UXA doesn't know how to
render to them, we should let glamor to do the validation.
