Cross-compilation of SkyBox.ps.slang fails

[nbentyNV]

The last statement in the Slang file is
return gTexture.Sample(gSampler, normalize(dir), 0);

Which is converted to the following illegal statement in GLSL
gTexture.Sample(gSampler, normalize(dir), float(0));

To reproduce run the Effects/EnvMap sample

Thanks. That should be an easy fix.

Note to self: hopefully just missing some __intrinsic(glsl, ...) modifiers in the stdlib.

Not an issue anymore. I was about to fix it and then I noticed that what I really want to use is SampleLevel. It works (but we still need to add the missing flavors)

[tangent-vector]

Cool. Let's leave this open so I can get to it sooner or later.

[tangent-vector]

Note to self: the "sample with clamp" operations seem to be a GLSL extension (sparse textures, IIRC), and not something built-in. If we need these they will have to be tagged to enable the right extension.

Closing. We are far past this point in cross-compilation support.
