Linux build missing mat_depthbias_shadowmap command

Details

Using the x86-64 - Chromium + 64-bit build on Linux with the CEFCodecFix.

mat_depthbias_shadowmap appears to be missing on the Linux build of Garry's Mod, env_projectedtexture lights suffer large loss in quality, especially when placed at a distance, and seems to stop working on models entirely.

FarZ and NearZ seem to act differently too, but I'm unsure if it's related or not.

It's not missing. Try using mat_info and see if m_ZBiasAndSlopeScaledDepthBiasSupported says yes.

m_ZBiasAndSlopeScaledDepthBiasSupported does turn up as yes. Attempting to use mat_depthbias_shadowmap results in "Unknown command: mat_depthbias_shadowmap" in the console.

Using Proton brings the command back (though there are color-banding and shading issues), but the loading times become exponentially longer to the point where it may as well be frozen.

I see that it is hidden on Linux/OSX and is set to 20 by default. Not sure if this value is actually used, the convar is defined in multiple places for some reason.

I am also unsure if unhiding the convar would have any benefit, as the rendering system on Linux is slightly different in many ways, which is why I suspect the default value is what it is on Linux, and why the convar is hidden in the first place.

Shadows on models seem mostly to work fine in Half-Life 2, but the convar is hidden there too, so I can't compare anything.

Hopefully there's a fix in the near future.
