[Intel-gfx] [PATCH 4/4] uxa/glamor: Create glamor pixmap by default.

[zhigang.gong at linux.intel.com]

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

As a pure glamor pixmap has a local texture rather than
bind a pixmap to a external BO. This can avoid some
unecessary flush, and can achieve better performance.
The testing on my machine shows that aa10text/rgb10text
get about 20-30% performance improvement.
