There is no way for us to ask for OpenGL 1.2.1 support. No big deal but it should exist a GLEW_VERSION_1_2_1 GLboolean to use.

    Here is the patch I'm proposing to resolve this.
    It's a bit unfortunate this wasn't done properly in the first place, but I'm
    reluctant to move the relevant 1.3 functionality into 1.2.1, in case there
    are applications relying on that. So there is no version check for 1.2.1,
    GLEW_VERSION_1_2_1 and GLEW_VERSION_1_3 are essentially
    the same version.
