X11 Direct Graphics Access extension library (development headers)

 libXxf86dga provides the XFree86-DGA extension, which allows direct
 graphics access to a framebuffer-like region, and also allows relative
 mouse reporting, et al. It is mainly used by games and emulators for
 games.
 .
 This package contains the development headers for the library found in
 libxxf86dga1. Non-developers likely have little use for this package.
