Bug#455388:

[Andres Mejia]

The check was originally intended to fix bug #435468, more
specifically, this error.

********************
ERROR: R_Upload32_3D: texture is too large (resizing is not supported)
********************
Error: Error during initialization
********************
ERROR: Received signal 11

********************
Recursive Sys_Error: Received signal 11

Looking at the code for R_Upload32_3D, it checks for
glConfig.max3DTextureSize, so the check in the script should actually
be for GL_MAX_3D_TEXTURE_SIZE.

Come to think of it, I don't like these checks in the wrapper scripts.
There should be checks within warsow itself.

Anyway, Evgeni, can you post the output of `glxinfo -l`?
