Add ShmImage, a shared memory Pixmap
...
Using the SHM extension of the X server saves us from sending ~1MB of
bitmap data to the server on many screen update operations for a
modestly sized terminal window.
SHM may not be available in some situations so we need to keep a
fallback that basically works. This is done via a helper enum
in xwin.rs.
I've removed the unused Pixmap class; the pixmap concept makes the
most sense for us only when SHM is available.

The spacing between glyphs seems too wide. Need to figure this out.
A bunch of the integer vs float changes in this diff were a result
of trying to run this down, but success has been limited, and in fact
the spacing has increased as a result of making this more correct(!)
