// PullExpressionsIntoFunctions: Certain GLSL expressions are not translatable as single
// expressions. Those that need to be translated into multiple expressions, or into one or more
// statements, are pulled into functions and replaced by a function call.
//
// This works by pulling all temporaries used inside of ternaries into global variables, which is
// fine because recursion is not allowed in GLSL. Function parameters are much more difficult to
// pull into globals, so they are just all passed to the new function.
//
// This makes all arbitrary ternaries, comma operators, outparams, and multielement swizzle
// assignments translatable into WGSL.
