*
* - Interactions with features not supported by the underlying
* ES 3.1 API and Shading Language, including:
* * gl_ClipDistance shader inputs and outputs.
* * "component" layout
* * location aliasing
* * fragment shader output "index" layout
* * fragment shader gl_FragDepth layout "depth*" qualifiers
* * double-precision scalars and vectors
* * matching across shader stages with different qualifiers (other
* than precision and "in"/"out").
* * References allowing or assuming more than one shader object per
* pipeline stage.
* * gl_PerFragment is not added (only exists in compatibility
* profile)."
