[Webkit-unassigned] [Bug 226660] [Metal ANGLE] Shaders with reserved metal keywords do not translate, nor do shaders with struct and variable names that are the same except prefixed by an underscore

--- Comment #3 from Kenneth Russell <kbr at google.com> ---
Note that the WebGL variant of GLSL ES reserves some keyword prefixes:
https://www.khronos.org/registry/webgl/specs/latest/1.0/#4.3

so you could safely rename any of these variables which collide with Metal's reserved ones by prepending for example "_webgl_" to it after the initial parse and validation.
