CrowLite beta2 (7/24/97)

Thanks to Troy "ArchVile" Mann <vile@grassy.nol.net> for lots of help with the area lighting

This program should run anywhere between 10%-300%
faster than the standard light.exe depending on 
the complexity of the map and the number of light 
sources, providing you vis the maps before running
fastlite on them. Also, it supports the Lightdis 
mods. Read below for details

***NEW*** Area Lighting
This is a really cool new feature i'm working on, it makes sky and lava
brushes emit light, thats right, the entire brush emits light. cool eh?
Be sure you actually use a sky brush and dont just change one side a normal
brush to a sky texture, it wont work if you do that. It's enabled by default
just use -noarealights to disable it. Before you can use area lighting you 
must use crowqbsp, it has do to with sky and lava surfaces not being split, 
also it must support transparent sky, and lava leafs. This is also very slow,
but using -areadensity can vastly affect the performance. Note: the amount of
light that the extures emit is fixed in this version, it will be configurable
in the future. 

*** Warning: area lighting does not work on maps that are not qbsped with
	     crowqbsp, sorry but maybe i can find someone with a good qbsp
	     to add my changes.

--- Usage ---
usage: crowlite [-novis] [-water] [-nopointlights] 
		[-noarealights] [-extra] [-dist num] 
		[-range num] [-areadensity num] bspfile

-novis			does not use visibility info, used for speed testing
			or debugging, also makes area lighting ever slower

-water			use this switch if your qbsp does not support 
			transparent water. If it does then you do not need
			to use this. Note: crowqbsp does support trans water

-nopointlights		skips standard point lights and only does area lighting

-noarealights		disables area lighting

-areadensity		this sets the resolution, and thus the quality, of the
			light that sky and lava brushes emit. Default value is
			1.0 for pretty good quality, lower values are worse 
			quality, higher values are better quality but slower.
			I would go no less than .7 and no higher than 2.5

new keys can be used to specify light entities' direction and fading.

** key "mangle" specifies light entities' direction. key must have 3 values.
  first value is "yaw" angle (degrees), second - "pich" angle, third - not used.
  dont mix with intermission camera's key "mangle" which specifies X, Y, Z of
  point where the intermission camera looks at.

  example:
  {
  "classname"	"light"
  "origin"	"384 192 256"
  "light"	"600"
  "mangle"	"90 -45 0"
  }

** key "wait" specifies light entities light fading. key must have 1 value.
  lower value makes light fade slower.
  actualy does the same that commandline parameter "-dist" but
  only for entities that have this key. commandline parameter "-dist"
  still works.

  example:
  {
  "classname"	"light"
  "origin"	"384 192 256"
  "light"	"600"
  "wait"	".5"
  }
