Break EXA ABI while we still can. Add coordinates to the UploadToScreen

    hook so we can upload a subset of a pixmap, and convert the current
    drivers to respect that. Use this support to directly UploadToScreen in
    exaGlyphs, providing a 47.4% +/-2.4% decrease in wall time for ls -lR
    programs/Xserver in an antialiased gnome-terminal on an M6 (n=3, caches
    hot). I would have bumped major version, only I can't tell what the
    EXA_VERSION_* is supposed to be doing as opposed to the module version.
