is also
shit slow). But as a display subbitmap _should_ only use different
texcoords,
it should be as fast as a regular display bitmap :o
That's why I don't get it. They're video bitmaps.
Looking at the code there is nothing that jumps out at me and says
that things should be slower for subbitmaps.
