illusion-arena-engine/code/renderer_oa/tr_shader.c
leilei- 04870d3a20 - r_roundImagesDown 2 - nonpowerof2 (NPOT) support. No extension checking added yet; use at your own risk! (intended for buffer effects) 
- r_parseStageSimple - working towards pcx2 support by loading shader stages with the texture last, to approximate blending functions by processing them into having alpha channels (or not, for opaque surfaces). Because I can.
- leifx filter change - indicate number of passes to the shader, so the pixel blurring order can be tweaked to further perfection (ridding the left pixel check as that happens)

===============
R_FindShader
Will always return a valid shader, but it might be the
default shader if the real one can't be found.
In the interest of not requiring an explicit shader text entry to
be defined for every single image used in the game, three default
shader behaviors can be auto-created for any image:
If lightmapIndex == LIGHTMAP_NONE, then the image will have
dynamic diffuse lighting applied to it, as apropriate for most
entity skin surfaces.
If lightmapIndex == LIGHTMAP_2D, then the image will be used
for 2D rendering unless an explicit shader is found
If lightmapIndex == LIGHTMAP_BY_VERTEX, then the image will use
the vertex rgba modulate values, as apropriate for misc_model
pre-lit surfaces.
Other lightmapIndex values will have a lightmap stage created
and src*dest blending applied with the texture, as apropriate for
most world construction surfaces.
Leilei TODO - and if it has a lightmapindex and no detail texture please
try to generate a generic detail stage for the sake of consistency with
the other textures with details so there's one big grainy world
(only if r_detailTextures 3)
TODO: if r_detailTextures 2, try to move the detail texture before the lightmap
stage and use filterblend , so we can use the multitexturing
pass performance advantage
