Is it?  IIRC, we don't want to store BMP files on disk because they
are extremely large compared to compressed formats, right?  So we have
to convert those files anyway, which leads to the loss of any speed
advantage, I believe.

PNG also supports this.

Ditto for PNG.

This is not a problem, I think.  FreeType itself already needs libpng;
using it doesn't add any new prerequisite.

Ah, ok.  Now I understand.  Yes, this makes sense.
