Subject: Use GL_VERSION_x_y to guard the enums for promoted extensions
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=f159ebc4120fb057c9d59efb0e5c7c36bff6f40a;p=libs%2Fgl.git

Use GL_VERSION_x_y to guard the enums for promoted extensions

The core names for enums are used in headers, and older systems might
have the extension present but too old core version.
