/*
* XFree86 driver for the Voodoo 2 using native X support and no
* Glide2. This is done for two reasons, firstly Glide2 is not portable
* to other than x86_32 which is becoming an issue, and secondly to get
* accelerations that Glide does not expose. The Voodoo 2 hardware has
* bit blit (screen->screen, cpu->screen), some colour expansion and
* also alpha (so could do hw render even!). Also can in theory use
* texture ram and engine to do arbitary Xv support as we have
* colour match on the 2D blit (ie 3D blit to back, 2D blit to front)
* along with alpha on the Xv 8) and with some care rotation of Xv.
*
* Alan Cox <alan@redhat.com>
*
* Derived from:
*
* XFree86 driver for Glide(tm). (Mainly for Voodoo 1 and 2 cards)
