* light: Add support for LIGHTING_E5BGR9.
This is not really finished. Currently mutually exclusive with
regular RGBLIGHTING, and not tested with external .lit file.
* light: replace HDR_PackResult with a version following the OpenGL spec
- add HDR_UnpackE5BRG9 for unpacking
- caller is now responsible for scaling 128 -> 1
- expose in header for tests
* light: move HDR_PackE5BRG9/HDR_UnpackE5BRG9 to common/litfile.hh
* build: std::powf not available in gcc
* common: move LoadLitFile to litfile.hh
* common: LoadLitFile: return hdr variant as well
* lightpreview: add an Exposure slider
* lightpreview: support hdr .lit's, wip
* tests: refactoring to set up testing for hdr lit's
* tests: add test for -hdr and -bspxhdr
* tests: fix LM_Sample to deal with styles correctly
* lightpreview: fix glsl error
* lightpreview: show dialog box for glsl compile errors

use stb_image_write for PNGs for better compression on bsp.json
add in code for spitting out a lightmap from a face. doesn't support other styles and such yet.
Fix q2rtx, needs to include lightstyle for nodraw for emissive invisibles with lightstyles
fix wal (for the 900th time)
auto-set -nolighting for -q2rtx
imglib now lives in common
fs 'load' split into two functions, where and load. the former allows you to query for and return archive & path for a given file, whereas the latter handles that for you.
use log verbose in light rather than own verbose flag
- there's still a couple failure cases - specifically base1 in the outdoor area has a side that wasn't able to match to a face
- the clip brush at the start of base1 gets cut into a bunch of pieces because of the whole "check for texinfo, compare and split into multiple pieces" thing, but I'm pretty sure it's just one single brush - we need to ignore the splitting thing on clip brushes since they don't care about texture
- triggers don't pull in a temp texture
- origin brushes?
