Well, I think !imgs->changed still transports the right semantics.

No idea if it would help much, but just skip everything (including
clearEOSD) and go directly to glNewList(eosdDispList, GL_COMPILE);
Much better would be a way to mark the glyphs that are already uploaded
somewhere (colour changes would still allow them to be reused btw), but
that would probably be much more work.
