Seth you hare a wizard! :)

 Checkout our new engine particle (tomazquake based) engine here:

 This work generating particles on sky and water surfaces. I think can be 
applied to light. Any iddea?

I am working on an enhanced light.exe for Quake 1 map compiling, and I
want it to properly light faces even when the two texture axes are not
perpendicular.  (Which won't happen in most editors, but can be done in
QuArK.)

Unfortunately light.exe seems to only pay attention to one texture axis
when casting light onto a skewed texture.  Perhaps a screenshot will
demonstrate this better than my description:

 * the back wall texture is skewed like this: /_/
 * the light on the back wall should look nice and round
 * the light on the near cube is okay because it isn't so skewed
 * the light on the yellow thing is slightly messed up in parts

I suspect that the problem is located in the ltface.c file of the
light.exe source code, most likely in the LightFace or CalcFaceVectors
function.

Any idea how I can fix this?

The modified light program I'm working on and the test map can be found
