Keith Packard fd439afdfe Add COMPOSITE change to fbCopyWindow (not needed yet)
Xnest was half-using midispcur and doing a bad job of it. Replace all of
    that code with mipointer which does a lot of the work.
Support DDXen which don't provide GetWindowPixmap, or which return NULL for
    the root pixmap.
