dga: Direct graphicaccess
Used to cause issue in vice and some other applications if not handled
carefully and configured properly in the application. But that's been
years ago so things might have changed here, too.
Since I don't know much about dga and its implications, I'll leave it in place
for now.
http://www.mplayerhq.hu/DOCS/HTML/en/dga.html is a good read.
Basically, it appears to be a method for doing dynamic screen resolution
switching (obsoleted by Xrandr) in combination with mapping video memory
directly into a userspace process (obsoleted by Xv, DRM+OpenGL). I doubt
it even works on any video card made in the past 10 years; and it
definitely wouldn't work on anything using KMS.
Ok, so after reading that, I'd rather remove support for that completely. But
it'll definitely stay optional, if we keep it.
