Fix bug that would cause SIGSEGV when a screen changed while it was
not visible.  The optimization being performed for invisible screens
was leaving the window redisplay data structures in an inconsistent
state.  The fix uses a less-agressive optimization that does all the
redisplay up to the screen matrix, but avoids transferring the changes
to the X window.
