Kevin Shanahan 462792e03b qbsp: rename node member valid->fillmark 
This is not a yes/no flag it's an integer mark to see if we have visited
the node within the same fill pass.

Kevin Shanahan d65dc77ac7 qbsp: lift the hullnum check out of MarkLeakTrail 
Makes it kind of obvious now that there is a bug here - if we have a small
leak in hull 0 or 1 which is sealed in hull 2 (due to brush expansion), then
we won't get a leak trail!

Kevin Shanahan 1432d99049 qbsp: cleanup texinfo flags before writing bsp 
The TEX_SKIP flag isn't needed and although it *shouldn't* upset any
engines, better to not write it out at all.

Well, even better to not write anything about the skip texture to the BSP
file, but need to re-organise things a bit more before that can happen.

Kevin Shanahan a8d8150791 light: implement the -gate option 
Precalculate the distance at which lights will fade to zero brightness.
For lights with inverse falloff, use the gate value to determine the
cut-off distance.  Use this value to cull samples and avoid the ray
tracing overhead.

Hopefully not too controversially, I am going to default this to "on" with
a gate value of 0.001. Unless you have > 1000 lights contributing
fractional light values across your map, this is not going to make any
visible difference.

Kevin Shanahan bea0f0f983 light: bsp_origin is just zero, don't need rel vector 
May as well keep dist as the actual distance and just call ScaledDistance
twice (poor function name, btw - it's effectively the equivalent of the
"fade gate" stuff)
