// The format of this file:
//   C++ style single-line comments are supported.
//   Leading whitespace is only for formatting and doesn't have semantic meaning.
//
//   Grouping:
//   Groups of functions are denoted by "GROUP BEGIN" and "GROUP END". Groups can be nested.
//   Groups can have metadata related to the group itself. This is given at the end of the GROUP
//   BEGIN line in JSON object format.
//   Example:
//     GROUP BEGIN <group name> {"shader_type": "FRAGMENT"}
//     GROUP END <group name>
//
//   Defaults:
//   Default metadata for functions can be set with "DEFAULT METADATA" followed by metadata in JSON
//   object format. The metadata is applied to all following functions regardless of grouping until
//   another "DEFAULT METADATA" line is encountered, or until the end of a top-level group.
//   Example:
//     DEFAULT METADATA {"opSuffix": "ComponentWise"}
//
//   Supported function metadata properties are:
//     "essl_level"
//         string, one of COMMON_BUILTINS, ESSL1_BUILTINS, ESSL3_BUILTINS and ESSL3_1_BUILTINS,
//         ESSL3_2_BUILTINS.
//     "glsl_level"
//         string, one of COMMON_BUILTINS, COMMON_BUILTINS, GLSL1_2_BUILTINS, GLSL1_3_BUILTINS,
//         GLSL1_4_BUILTINS, GLSL1_5_BUILTINS, GLSL3_3_BUILTINS, GLSL4_BUILTINS, GLSL4_1_BUILTINS,
//         GLSL4_2_BUILTINS, GLSL4_3_BUILTINS, GLSL4_4_BUILTINS, GLSL4_5_BUILTINS, and
//         GLSL4_6_BUILTINS.
//     "opSuffix"
//         (optional) string, suffix to add to EOp code.  The op is derived from the function name,
//         and this suffix is applied to disambiguate between functions of the same name but in
//         different groups.
//     "suffix"
//         string, suffix that is used to disambiguate C++ variable names created based on the
//         function name from C++ keywords, or disambiguate two functions with the same name.
//     "essl_extension"
//         string, ESSL extension where the function is defined.
//     "essl_extension_becomes_core_in"
//         string, ESSL level where functions from this extension have become core.
//     "glsl_extension"
//         string, GLSL extension where the function is defined.
//     "hasSideEffects"
//         boolean, can be used to mark a function as having side effects. Functions with an out or
//         inout parameter are automatically treated as having side effects.
//         TODO: Since the removal of the CallBuiltInFunction operator, all functions that were
//         previously given that operator have been marked as having side effect to preserve the
//         prior behavior.  Many of these functions don't actually have side effects, and can be
//         cleaned up.  http://anglebug.com/6061
//         TODO: dFdx, dFdy and fwidth were explicitly marked as having side-effects by Olli.  They
//         don't actually have side effects, and it may have been done to work around a bug.  Try
//         and clean these up.  http://anglebug.com/6061
//
//   Function declarations:
//   Lines that declare functions are in a similar format as in the GLSL spec:
//     <return type> <function name>(<param type>, ...);
//   Parameter types can have "out" or "inout" qualifiers.
