Detailed Description

Jot interface for loading OpenGL extensions.

Statically constructed at run-time and initializes a set of extensions to GL. The public queries will return the availability of the extensions, but the calls to extensions must still be placed in ifdef's. e.g.

if (gl_arb_multitexture_suported()) { ifdef GL_ARB_multitexture do_stuff(); endif }

Note:
The general is_extension_supported() is not exposed, since win32 requires that extension functions be declared as pointers, and fetched from the opengl icd. The baked in extension queries in this class indicate if an extension is supported AND that the functions are ready to call.
