[off-topic ;-)]

The effect is compounded. I see why you make the textures dark, and my
system is also broken, which makes them seem even darker.

XF86_SVGA, the Xserver I use, assumes monitor gamma 1.0, and real
monitors don't have gamma anything like this.  My old compaq 14" had
gamma around 2-ish -- this applevision beast has gamma nearly 3!

Quake runs fine (with appropriate settings of the SSTV2_GAMMA var),
and if I really want to look at a screenshot of a dark game
(e.g. quake) I save it to disk and display it with display -gamma
3. But web browsing is annoyingly dark.

It will all be fixed when I upgrade to X 4, I believe, which has
proper gamma correction (and even uses VESA to ask the monitor its
gamma value).
