I have packaged up my dmxdirect SPU for public release in hope that it
will be useful to others.
I'd like it to be included with Chromium under Chromium's license. I
will also distribute it independently under the GPL via arrummzen.net
(I think that is legal, two separate distributions of the same package
under different licenses?)

The purpose of the dmxdirect SPU is to allow the direct use of the 3d
capabilities of a single display backend while in a DMX environment.
Tilesort allows one to use the capabilities of all displays at the
same time, at the cost of performance and compatibility. dmxdirect
restricts the OpenGL output to a single display, but gives much better
performance and compatibility. It is useful for running apps that will
not work with tilesort in a DMX environment, as well as debugging and
testing.

Attached is the dmxdirect.tar.bz2 which contains the dmxdirectspu,
some notes, and a patch needed for it to work with the main Chromium
source distribution.

Thank you for your time,
James Steven Supancic III
