Wrap switch statements in blocks in HLSL If variables are declared inside a GLSL switch statement, they are scoped until the end of the switch statement. This is not compatible with HLSL rules, where the scoping is until the end of the case. To work around this, wrap switch statements in a block that declares the variables in HLSL. This is done after most other transformations done to the AST are complete, since some of the other transformations may introduce temporary variables.
