- Fix texture uploads. Now request/upload a single buffer at a time,
improves available space sharing with other contexts (rather than
grabbing most of it for a single texture upload). Really need larger
buffers for better efficiency, this is coming...
- Fix glean makeCurrent failure.
Need to track down some strangeness in the texture LRU mechanism seen with
Q3 High Quality, but apart from that we're looking in good shape to
merge with the trunk.

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).
The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:
1. The DRM provides synchronized access to the graphics hardware via
the use of an optimized two-tiered lock.
2. The DRM enforces the DRI security policy for access to the graphics
hardware by only allowing authenticated X11 clients access to
restricted regions of memory.
3. The DRM provides a generic DMA engine, complete with multiple
queues and the ability to detect the need for an OpenGL context
switch.
4. The DRM is extensible via the use of small device-specific modules
that rely extensively on the API exported by the DRM module.
Documentation on the DRI is available from:
http://precisioninsight.com/piinsights.html
