Zack Middleton 350b8f9c7c Restore OpenGL 1.1 support (GL_CLAMP) ... GL_CLAMP (clamp to border) was changed to GL_CLAMP_TO_EDGE in 2008 (f2baf359). In 2018 (ce1d5406) I made OpenGL 1.2 be required since GL_CLAMP_TO_EDGE is used. Restore support for GL_CLAMP in order to support OpenGL 1.1 like vanilla Quake 3 does. This should allow using the default Microsoft Windows GDI Generic OpenGL 1.1 driver (untested but it won't fail the version check at least). From gpuinfo.org, it looks like drivers stopped advertising support for GL_SGIS_texture_edge_clamp so use a version check in addition to the extension check. r_allowExtensions 0 disables using GL_CLAMP_TO_EDGE in the opengl1 renderer. GL_CLAMP support wasn't added to the opengl2 renderer.		2019-05-28 22:44:57 -05:00
