/**
* Native bindings to the ARB_shading_language_include extension.
*
* This extension introduces a {@code #include} GLSL directive to allow reusing the same shader text in multiple shaders and defines the semantics and syntax of
* the names allowed in {@code #include} directives. It also defines API mechanisms to define the named string backing a {@code #include}.
*
* Introduction
*
* The GLSL {@code #include} mechanism looks up paths in a tree built through the OpenGL API. This appendix describes the syntax and semantic model of the tree and
* paths into the tree. How the tree is used is up to users of the tree, like the OpenGL API or GLSL.
*
* The Tree
*
* The tree is a singly rooted hierarchy of tree locations. The root may have one or more child locations, and any location may in turn have its own
* children. Except for the root, each location has exactly one parent; the root has no parent.
*
* Paths into the Tree
*
* The locations in the tree are created or looked up by path strings. The path string "/" locates the root of the tree. The path "/foo" locates the child
* "foo" of the root. Formally, a valid path is a sequence of tokens delimited by the beginning of the string, by the path-separator forward slash ( / ),
* and by the end of the string. The string "foo/bar" has two tokens; "foo" and "bar". The string "/foo/./bar" has 3 tokens; "foo", ".", and "bar". The
* string "/foo/.." has two tokens; "foo" and "..". The string "/foo/.bar" has two tokens; "foo" and ".bar". A path is invalid if
*
*
* - {@code path} contains any characters not listed in Section 3.1 "Character Set", or the double quote character, or angled brackets, or any white
* space characters other than the space character.
* - {@code path} has consecutive forward slashes ( // ); "/foo//bar" is not valid (zero length tokens are not allowed).
* - {@code path} ends with a forward slash ( / )
* - {@code path} contains no characters.
*
*
* There are no path escape characters, so there is no way to get the forward slash delimiter within a single token.
*
* When using a path to lookup a tree location, the path tokens are used to walk the tree. The initial location to start the walk is specified by the user
* of the tree and is updated as follows by the tokens in the path. (Paths starting with "/" will start at the root.) Taken left to right:
*
* The token ".." walks to the parent. Or, if already at the root, then the location remains at the root.
*
* The token "." leaves the location unchanged.
*
* Any other token is considered the name of a child of the current location, and walks to that child. (If there is no child of that name, this may result
* in a failed lookup or in the child being created, as specified by the user of the tree for the operation being performed.)
*
* Associated Strings
*
* Each location in the tree can have an additional string associated with it (that a user like the {@code #include} mechanism can use as an included string). This
* is true even for locations that have children: "/foo/bar" can exist in the tree at the same time that "/foo" has an additional string associated with
* it. Typically, when a path is used to find a location in the tree, it is for the purpose of returning this associated string.
*
* Hence, the tree can be built from a collection of (path,string) pairs, where path is a string establishing the existence of a location in the tree and
* string is the string associated with the node. Details of how to do this are specified by the user of the tree.
*
* Requires GLSL 1.10.
