[ITP] VirtualGL 2.6.3

[DRC]

I intend to package the client for VirtualGL, a toolkit that adds
server-side GPU-accelerated OpenGL rendering capabilities to existing
remote X or X proxy environments.

VirtualGL is currently provided by various Linux distributions and FreeBSD:

It is licensed under the wxWidgets Library License v3.1:
