HLSL based Reflective Bezel for MAME

[Justin]

Not sure how much interest this will draw, but I am a big fan of HLSL versus GLSL/BGFX when running MAME, and there arent any reflective bezel shaders out there for HLSL.  So, I have taken this upon myself to tweak the native post.fx HLSL file to add a reflection, combined with a MAME artwork file for the Bezel bitmap itself, in "additive" blend mode to achieve something very very promising so far...   

Still some huge hurdles to overcome given the nature of hardcoded shader chain order in HLSL....

Looking for help from experienced HLSL coders out there to get this finished and polished.
