-// Constructors and operators introduced in GLSL 1.20 - mostly on new
-// (non-square) types of matrices.
-//
-// One important change in the language is that when a matrix is used
-// as an argument to a matrix constructor, it must be the only argument
-// for the constructor. The compiler takes care of it by itself and
-// here we only care to re-introduce constructors for old (square)
-// types of matrices.

-//
-// This file defines nearly all constructors and operators for built-in data
-// types, using extended language syntax. In general, compiler treats
-// constructors and operators as ordinary functions with some exceptions.
-// For example, the language does not allow functions to be called in
-// constant expressions - here the exception is made to allow it.
-//
-// Each implementation provides its own version of this file. Each
-// implementation can define the required set of operators and constructors
-// in its own fashion.
-//
-// The extended language syntax is only present when compiling this file.
-// It is implicitly included at the very beginning of the compiled shader,
-// so no built-in functions can be used.
-//
-// To communicate with the implementation, a special extended "__asm" keyword
-// is used, followed by an instruction name (any valid identifier), a
-// destination variable identifier and a list of zero or more source
-// variable identifiers.
-//
-// A variable identifier is a variable name declared earlier in the code
-// (as a function parameter, local or global variable).
-//
-// An instruction name designates an instruction that must be exported
-// by the implementation.  Each instruction receives data from source
-// variable identifiers and returns data in the destination variable
-// identifier.
-//
-// It is up to the implementation how to define a particular operator
-// or constructor. If it is expected to being used rarely, it can be
-// defined in terms of other operators and constructors,
-// for example:
-//
-// ivec2 __operator + (const ivec2 x, const ivec2 y) {
-//    return ivec2 (x[0] + y[0], x[1] + y[1]);
-// }
-//
-// If a particular operator or constructor is expected to be used very
-// often or is an atomic operation (that is, an operation that cannot be
-// expressed in terms of other operations or would create a dependency
-// cycle) it must be defined using one or more __asm constructs.
-//
-// Each implementation must define constructors for all scalar types
-// (bool, float, int).  There are 9 scalar-to-scalar constructors
-// (including identity constructors). However, since the language
-// introduces special constructors (like matrix constructor with a single
-// scalar value), implementations must also implement these cases.
-// The compiler provides the following algorithm when resolving a constructor:
-// - try to find a constructor with a prototype matching ours,
-// - if no constructor is found and this is a scalar-to-scalar constructor,
-//   raise an error,
-// - if a constructor is found, execute it and return,
-// - count the size of the constructor parameter list - if it is less than
-//   the size of our constructor's type, raise an error,
-// - for each parameter in the list do a recursive constructor matching for
-//   appropriate scalar fields in the constructed variable,
-//
-// Each implementation must also define a set of operators that deal with
-// built-in data types.
-// There are four kinds of operators:
-// 1) Operators that are implemented only by the compiler: "()" (function
-//    call), "," (sequence) and "?:" (selection).
-// 2) Operators that are implemented by the compiler by expressing it in
-//    terms of other operators:
-//    - "." (field selection) - translated to subscript access,
-//    - "&&" (logical and) - translated to "<left_expr> ? <right_expr> :
-//      false",
-//    - "||" (logical or) - translated to "<left_expr> ? true : <right_expr>",
-// 3) Operators that can be defined by the implementation and if the required
-//    prototype is not found, standard behaviour is used:
-//    - "==", "!=", "=" (equality, assignment) - compare or assign
-//      matching fields one-by-one;
-//      note that at least operators for scalar data types must be defined
-//      by the implementation to get it work,
-// 4) All other operators not mentioned above. If no required prototype is
-//    found, an error is raised. An implementation must follow the language
-//    specification to provide all valid operator prototypes.

- * Describes where data/variables are stored in the various register files.
- *
- * In the simple case, the File, Index and Size fields indicate where
- * a variable is stored.  For example, a vec3 variable may be stored
- * as (File=PROGRAM_TEMPORARY, Index=6, Size=3).  Or, File[Index].
- * Or, a program input like color may be stored as
- * (File=PROGRAM_INPUT,Index=3,Size=4);
- *
- * For single-float values, the Swizzle field indicates which component
- * of the vector contains the float.
- *
- * If IsIndirect is set, the storage is accessed through an indirect
- * register lookup.  The value in question will be located at:
- *   File[Index + IndirectFile[IndirectIndex]]
- *
- * This is primary used for indexing arrays.  For example, consider this
- * GLSL code:
- *   uniform int i;
- *   float a[10];
- *   float x = a[i];
- *
- * here, storage for a[i] would be described by (File=PROGRAM_TEMPORAY,
- * Index=aPos, IndirectFile=PROGRAM_UNIFORM, IndirectIndex=iPos), which
- * would mean TEMP[aPos + UNIFORM[iPos]]
