Zhigang Gong f62f4d53ef glamor_glyphs: When dst arg point to a NULL buffer, dont't flush. 
This is a corner case, when we render glyphs via mask cache, and
when we need to upload new glyphs cache, we need to flush both the
mask and dest buffer. But we the dest arg may point to a NULL buffer
at that time, we need to check it firstly. If the dest buffer is NULL.
Then we don't need to flush both the dest and mask buffer.

This commit fix a potential crash.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:
