As for this patch and all subsequent patches, we (at $DAYJOB) discussed
during our Review Club the idea of not supporting .rev files altogether.
Firstly, because of this bug, we cannot fully trust .rev files anymore.
And even if we decided to trust it (or to trust it after some
verification step that I can't think of), that file would only be useful
for a short time until a regularly scheduled maintenance step
regenerates the bitmaps anyway.

That would also simplify the code slightly and eliminate the need to test a
variety of cases - so we probably wouldn't need the t/lib-bitmap.sh file
introduced in patch 6. I'll hold off on reviewing the rest of the
patches for now, since they may substantially change if we decide to
stop supporting .rev files.
