recipes-graphics: Add more detailed SUMMARY and DESCRIPTIONS

Add more detailed SUMMARY and DESCRIPTIONS to various graphics and
graphics related components.  I've recently gotten question from users
what something is, or why it was needed.. this should go a long way toward
answering those questions.

Many of the descriptions were taken directly from the upstream location,
where one was not available the Debian packages were consulted for
information.

-DESCRIPTION = "X11 damaged region extension library"
+SUMMARY = "Xdamage: X Damage extension library"
+
+DESCRIPTION = "'Damage' is a term that describes changes make to pixel \
+contents of windows and pixmaps.  Damage accumulates as drawing occurs \
+in the drawable.  Each drawing operation 'damages' one or more \
+rectangular areas within the drawable.  The rectangles are guaranteed to \
+include the set of pixels modified by each operation, but may include \
+significantly more than just those pixels.  The DAMAGE extension allows \
+applications to either receive the raw rectangles as a stream of events, \
+or to have them partially processed within the X server to reduce the \
+amount of data transmitted as well as reduce the processing latency once \
+the repaint operation has started."
