Mesa Hardware Device Driver for ATI Rage Pro
Copyright (C) 1999 Gareth Hughes <garethh@bell-labs.com>


IMPORTANT
---------

You must disable font and pixmap caching for the X server, otherwise there won't
be any memory for 3D windows.  If you don't do this, the first 3D app will crap
on top of your text.  Someone should allocate this properly, so 8mb cards could
still use the caches.

Your device entry in XF86Config should look something like this:
  

Section "Device"
    Identifier  "Mach64 GB"
    VendorName  "Unknown"
    BoardName   "Unknown"
    Option	"no_font_cache"
    Option	"no_pixmap_cache"
    #VideoRam    4096
EndSection


Supported architectures:
------------------------

The driver has been reported to work on the following architectures:
Linux/x86
FreeBSD/x86


RAGE PRO HARDWARE LIMITATIONS
-----------------------------

While there are registers for all the mip mapping controls, the actual hardware doesn't
work, so no attempt is made to implement it.

RagePro can't fog and alpha blend or alpha test at the same time.
In fact, it can't have a texture marked as using alpha and fog at the same time.

(Can it bilinear and fog?)

RagePro can't bilinear filter and alpha blend (it can color blend) at the same time.
This is not made clear in the specs.

RagePro can't support GL_BLEND texture environment.

Destination alpha never gets a modulated value, only texel or fragment, so GL_MODULATE
texture environment with destination alpha can be wrong.

I think there is a problem with interpolating alpha in multitexture.

I think there is a problem with color plane write masks with blending
