Description Shane 2005-11-07 05:18:25 EST 
Dynamic lights are not blocked by a surface. Surfaces are effected that have no line of sight to the light.

This patch checks which side of a surface a light is; if it is behind the surface the dlight is turned off for that surface.

It should be noted, there is still a bug in dynamic lights. This patch fixes part of the problem; but dynamic lights still pass through surfaces and may light correct facing surfaces on the other side.

Committed, but linked to r_dlightBacks and minor performance improvements.

Setting a QA contact on all ioquake3 bugs, even resolved ones. Sorry if you get a flood of email from this, it should only happen once. Apologies for the incovenience.
