look a bit better (no flickering) by using the stencil buffer. Does
not work when `gl1_stereo` is `3`, `4` or `5`.
* **gl1_waterwarp**: Intensity of the "squeeze/stretch" effect on the
FOV when diving underwater. Can be any floating point number, `0`
disables it (Vanilla Quake II look). Default `1.0`.
* **gl1_lightmapcopies**: When enabled (`1`), keep 3 copies of the same
lightmap rotating, shifting to another one when drawing a new frame.
Meant for mobile/embedded devices, where changing textures just shown
