Fwd: [mythtv] blurry osd colour text for Xv output

[Geoffrey Kruse]

I have a fair amount of experience with openGl, but mostly with 3d 
virtual environments.   I have no idea how one might go about writing 
an openGL-based video output class.  Do you mean to use openGl instead 
of xv?  ie would you draw each frame as a texture on a quad?  Then what 
about video cards without hardware openGL support like most of the sis 
chips?
