You mean you want to change Load_GL_version_2_0 to also call Load_GL_version_1_5 under the hood, and then Load_GL_version_1_5 to call Load_GL_version_1_4 under the hood and so on? I guess that's Ok, go for it. Be aware that this will *not* work for OpenGL 3.x versions, where 3.0 deprecates and 3.1 removes some functions. Since 3.1, OpenGL versions are *not* guaranteed to be backwards compatible. Programmer will have to call Load_GL_version_3_1 and Load_GL_version_2_0 (or check ARB_compatibility) separately, since these are orthogonal. I guess this is the advantage of current approach: it doesn't assume that OpenGL versions are backwards compatible, and indeed they don't have to be since 3.1. But for GL 2.x and lower, sure, this will work fine.
