fcf46b39d8 Attempt to fix remaining transparency issues
All transparency-related config has been reverted back to how it was in
2020.3 for maximum compatibility. This is not ideal for HDR but we will
figure something out.

In HDR, transparent AC objects must be marked with model-transparent or
model-combined-transparent. glTF objects are automatically assigned the
correct Effects.

9f39644199 HDR: Optimize the G-Buffer and do not separate the occlusion texture
- The G-Buffer layout has been redesigned to be 96 bits per pixel. There are 24
unused bits that can be used for extra material parameters later (like
clearcoat).
- Add better debug views for the G-Buffer.
- Use octahedron normal encoding. This yields the same results as the previous
method but uses 16 bits less.
- Use rg11fb10f for the environment mapping cubemaps.
- Tweak the shadow mapping parameters and add a colored debug mode.
- Only render shadow maps for objects that inherit from model-default.eff or
model-pbr.eff instead of having a fallback Effect. Now transparent objects
should be ignored (if they are marked as such with model-transparent or
similar).
- Remove the separate occlusion texture. Now the PBR Effect expects a single
texture where R=occlusion, G=roughness and B=metallic.

b650a0eb51 Make sure shaders are disabled as long as /sim/rendering/shaders/quality-level is 0 or non existing.
This should help those checking out models in fgviewer
To enable effects in fgviewer run it with:
fgviewer --prop /sim/rendering/shaders/quality-level -1
Also fix random buildings not showing up when model shader was set to 0 and generic was enabled.

d43770ab58 Effects/model-default.eff move skydome to technique 5 to provide more headroom
Effects/model-combined.eff fix techniques numbering. Make active under rembrandt too. add model-combined-deferred as a stub for now for specific
Rembrandt use.
Users of model-combined with normalmaps should change the technique number to 9, and duplicate that entry for technique 8.
Fix some longstanding png warnings. Provide null_reflectdir.png for model-combined
This should fix part of bug #726

564c69e10a Issue 209: fix up inheritance of color mode uniform in material animation effect
The overriding of the color mode uniform in the default model effect
wasn't working. It's difficult to override the individual properties
of techniques, especially if their names aren't unique. So, I changed
the model-default effect to use a parameter for the color-mode
uniform; material-off.eff and material-diffuse.eff override that.

d27174028e shader optimizations
Use two-pass rendering for some shaders to reduce the cost of expensive shaders.

Implement some material animations using a shader uniform.

Eliminate use of gl_FrontFacing. It's too buggy on ATI/ Macintosh.

971b6c3ef2 light two-sided polygons
Also, remove model-default.frag; for the moment one fragment shader works for
both terrain and models.
