DRI3 WSEGL plugin for TI SGX

Hi All,

I have implemented a WSEGL plugin library for Imagination's PVR driver for SGX, which allows using SGX via DRI3. In other words, it is one piece in the puzzle of using SGX with X11.

The project is not production quality, as I have not had time to perfect it (and, to be honest, I'm not exactly an expert on X), but now that I finally got all the permissions to publish it, I'm doing just that to allow other people to use it and help making it fully usable.

You can find the code and a more detailed description here:

Hopefully with this code now public, we can get an SGX and GC320 accelerated X11 on TI devices.
