Could we do it the old-fashioned way ("git format-patch" on one side, "git am"
on the other)? Don't know when I'd get my freedesktop gitlab registration
back... attached.
Do you want the other one below about large memory allocated for bitmaps? For
now this seems to do it (without breaking adobe-made/sourced svg fonts) , but
until we see more svg fonts, we aren't sure. I think we probably should put a
stop on insanely large bitmaps (e.g. doing 12000x15000 instead of 12x15)
anyway, elsewhere.
