glamor: Improve the performance of line fallbacks.

If the lines aren't solid-filled vert/horiz solid-filled rectangles,
we fall back.  libreoffice has some diagonal lines, and the
performance of the fallback path was atrocious.  Just fall back to
mi's spans instead, so that we don't do an upload/download.

Improves x11perf -seg100 by 863.652% +/- 9.8968% (n=5)
