* suitable glDeleteXxx function is called on it;
* - the DeleteRequested status, which is has from when the suitable glDeleteXxx
* function is called on it to when it is no longer referenced by other OpenGL
* objects. For example, a texture that is attached to a non-current FBO

// Usage:
// ===========
//
// To create a new type from a set of GLenums do the following:

// STRONG_GLENUM_BEGIN(TypeName)
// STRONG_GLENUM_VALUE(ENUM1),
// STRONG_GLENUM_VALUE(ENUM2),
// ...
// STRONG_GLENUM_END()

// Important Notes:

//
// Boolean operators (==, !=) are provided in an effort to prevent some mistakes

//
// if (myNewType == STRONG_GLENUM_VALUE(SOME_ENUM))
// ...
//
// The operators will assert that STRONG_GLENUM_VALUE(SOME_ENUM) is a value that myNewType

//
// A get() method is provided to allow access to the underlying GLenum. This

// Definitely XXX - DO NOT DO - XXX:
//
// if (myNewType.get() == STRONG_GLENUM_VALUE(SOME_ENUM))

//

// operators. If you see code like this it should be treated with suspicion.
//
// Background:
// ===========
//
// This macro is the first step in an effort to make the WebGL code safer.
// Many of the different functions take GLenum as their parameter which leads
// to bugs because of subtle differences in the enums purpose. For example there
// are two types of 'texture targets'. One is the texture binding locations:
//
// GL_TEXTURE_2D
// GL_TEXTURE_CUBE_MAP
//
// Yet, this is not the same as texture image targets:
//
// GL_TEXTURE_2D
// GL_TEXTURE_CUBE_MAP_POSITIVE_X
// GL_TEXTURE_CUBE_MAP_NEGATIVE_X
// GL_TEXTURE_CUBE_MAP_POSITIVE_Y
// ...
//
// This subtle distinction has already led to many bugs in the texture code
// because of invalid assumptions about what type goes where. The macro below
// is an attempt at fixing this by providing a small wrapper around GLenum that
// validates its values.
//
// Comparison between STRONG_GLENUM's vs. enum classes
// ===================================================
//
// The present STRONG_GLENUM's differ from ordinary enum classes
// in that they assert at runtime that their values are legal, and in that they
// allow implicit conversion from integers to STRONG_GLENUM's but disallow
// implicit conversion from STRONG_GLENUM's to integers (enum classes are the opposite).
//
// When to use GLenum's vs. STRONG_GLENUM's vs. enum classes
// =========================================================
//
// Rule of thumb:
// * For unchecked GLenum constants, such as WebGL method parameters that haven't been
// validated yet, use GLenum.
// * For already-validated GLenum constants, use STRONG_GLENUM's.
// * For custom constants that aren't GL enum values, use enum classes.
