Fix various corner cases with expression dependencies. There was a potential problem if variables were invalidated and SPIR-V read expressions which depended on other expression which in turn depended on the invalidated variable. Also fixes issue where variables were considered immutable if they were forwardable. This allowed some incorrect optimizations to slip through. 2016-07-12 12:33:04 +00:00			`#version 450`

Implement workaround for textureLod on 2D array shadow. This does not exist in GLSL, but it exists in HLSL if LOD == 0.0. 2017-06-23 07:44:41 +00:00			`layout(location = 0) in float v0;`

Defer parenthesis generation until needed. Previously, we would generate parentheses proactively when generating binary ops, however, this leads to uglier code and hits warnings in compilers when used as a conditional. 2016-12-05 09:22:54 +00:00			`FragColor = (_17 + b) * b;`
