Mesa recently updated the <GL/glext.h> header version to Khronos version 85. This caused the PFNGLMULTITEXCOORD2FPROC definition to be moved out of the GL_VERSION_1_3_DEPRECATED block. However, since <GL/gl.h> also defines GL_VERSION_1_3 to 1, the definitions in <GL/glext.h> are then not enabled, thus leaving PFNGLMULTITEXCOORD2FPROC undefined as well. Provide a PFNGLMULTITEXCOORD2FPROC replacement as an interim solution for newer versions of the <GL/glext.h> header.
