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 = "The composite extension provides three related \
+mechanisms: per-hierarchy storage, automatic shadow update, and external \
+parent.  In per-hierarchy storage, the rendering of an entire hierarchy \
+of windows is redirected to off-screen storage.  In automatic shadow \
+update, when a hierarchy is rendered off-screen, the X server provides \
+an automatic mechanism for presenting those contents within the parent \
+window.  In external parent, a mechanism for providing redirection of \
+compositing transformations through a client."
