AnyOldName3 98b2d5d921 Make shadow debug HUD thread-safe 
* Double buffer the frustum uniforms.
* Don't mess with the debug geometry's StateSet.
* Change two-element vectors to arrays so the size is explicit.

AnyOldName3 12044a607b Only alpha-test shadows when necessary 
Previously we always discarded shadow map fragments if the alpha channel of the output would have been low, but there were some (modded) assets that have non-one alpha but have testing or blending disabled so end up opaque anyway. This lets the shadows of those objects match.

AnyOldName3 15547750ba Correct behaviour of use front face culling setting to not use back face culling either when disabled. 2019-02-01 00:29:13 +00:00
AnyOldName3 d82c85913a Don't bother multiplying a matrix by its inverse and applying that to the light direction. 
Hopefully this will improve numerical stability and reduce shadow flicker a little.
