There would need to be a *lot* of pre-cached glyphs, for the all the
different fonts, font sizes, rotations, etc.  You want sub-pixel perfect
rendering of font glyphs no matter what the transformation is - can
OpenGL do that?

Yes, WGL is Windows OpenGL.  AGL is Apple OpenGL.  XGL is X Windows
OpenGL.  Xagl/Xwgl are the names of the server software, not the
protocol, because that would just be silly.  ;-)
