We should let the renderer decide what's better.

Currently no bitmaps are supported by the AGG renderer. I still have
to study that. The flexibility of AGG makes it difficult to learn. For
example, there are at least ten (!) different methods of
rotating/rescaling a image available. The good thing is that gradients
work very similar to bitmaps. So, when one of them works, the other
should be easy to implement.

Identical bitmaps? For glyphs that look identical?

Do we still need the Cairo backend (provided that AGG works)? Is there
any really working backend except for the OpenGL one?

Anyway, we could use the AGG routines to draw the bitmap cache
in-memory even for the OpenGL backend. That would make everything much
easier.

Can someone verify that the AGG licence allows us to integrate AGG
into the Gnash source tree?
