2015-12-10 TyrUtils-ericw 0.15.4 release

New features:

* light: new "-parse_escape_sequences" command-line flag. 
         The "\b" escape sequence toggles red text on/off, you can use this
         in any strings in the map file. 
         e.g. "message" "Here is \bsome red text\b..."
* light: new "-surflight_dump" command-line flag. Saves the lights generated
         by surfacelights to a "mapname-surflights.map" file.
* light: new "_sunlight3" and "_sunlight3_color" keys. Same as "_sunlight2", 
         except creates suns on the bottom hemispere ("_sunlight2" creates
         suns on the top hemisphere.)
* build: support compiling with Visual Studio

Bugfixes:

* light: fix antilights (broken in last release)
* light: fix _mincolor to accept 0-1 float colors
* light: fix surface lights on rotating bmodels from incorrectly spawning
         lights near the origin
* qbsp: log coordinates for CheckFace errors

        compatibility
* qbsp: remove 128 char limit on entity key/value values

spotlights based on the surface normal

* light: add "-sunsamples" flag to control number of samples for
_sunlight_penumbra and _sunlight2
* qbsp: add "-epsilon" option to control ON_EPSILON, from txqbsp-xt

the txqbsp-xt version.

* qbsp: print coordinates for "New portal was clipped away" warning

2015-08-09 TyrUtils-ericw 0.15.2 release

* qbsp: add "-maxNodeSize" option, from txqbsp-xt. Defaults to 1024. Makes large
        maps process much faster and should generate better bsp trees.
        If it causes a problem disable with "-maxNodeSize 0"
* qbsp: make "mixed face contents" and "degenerate edge" non-fatal, from txqbsp-xt
* qbsp: make "-oldaxis" the default. new "-nooldaxis" flag to get the previous behaviour.
* light: add "-surflight_subdivide" flag to control amount of surface lights created
* light, vis: use below normal process priority on Windows
* light: allow negative surface light offset
* light: average the lit file color components to generate the bsp lightmap value.
         TODO: use a perceptually weighted average.
* light: fix lighting of hipnotic rotating entities.
* light: fix crash in "Bad texture axes on face:"
* light: fix surface lights being mistakenly duplicated
* light: add "-onlyents"
* light: add "-dirtangle" setting to control dirtmapping cone angle, default 88 degrees.

2015-07-09 TyrUtils-ericw 0.15.1 release

* light: .lux file support from Spike, for deluxemapping
* light: add gamma control with -gamma flag and "_gamma" key

  fix an issue with fence texture coords.
* light: support switchable lights with any light* classname, not just "light"
* light: fix debugging spam output from last build

2015-05-01 TyrUtils-ericw snapshot

* light: fix hang when using _deviance, make _samples default to 16 when
  _deviance is set.
* light: fix for always generating a .lit file when surface lights are used

2015-04-29 TyrUtils-ericw snapshot

* qbsp: fix broken -onlyents flag
* qbsp: fix texture offset on rotate_object, so they match in the
 editor. Added "-oldrottex" flag to revert to old behaviour. From txqbsp-xt.

2015-04-27 TyrUtils-ericw snapshot

new features:
* light: fence texture tracing, for bmodels with "_shadow" "1"
* light: surface light support via "_surface" "texturename" light key

convenience:
* light: respect "_dirt" "-1" bmodel key in -dirtdebug mode
* light: allow setting "-dist" and "-range" command-line flags in worldspawn
  ("_dist", "_range")
* light: accept "_sunlight_mangle" as an alternative for "_sun_mangle"

other:
* all: increase stack size to 8MB. Fixes qbsp crash with bbin1.map on Windows,
  light crashes.
* qbsp: switch to hardcoded MAX_MAP_PLANES (262K), speeds up map file loading
  phase.
* qbsp: MakeFaceEdges: accelerate with a hash table to avoid slow O(n^2) search
  for edges
* qbsp: ChooseMidPlaneFromList: fix off-by-one error in axial plane test. On
  the first SolidBSP pass, gives fewer split nodes on bbin1.map (128k vs 199k)
* light: MatchTargets: disable copying "style" key/value from a light to the
  entity that targets it. Don't see any point, and causes problems if "style"
  is meaningful for the targetting entity (e.g. a monster).
