Christoph Oelckers	b61ef3a107	- bumped minimum supported OpenGL version to 1.4. The engine was already using several 1.3 and 1.4 features which would have caused problems on 1.2. ... - removed gl_vid_compatibility. With the bump to 1.4 no hardware requiring this flag is supported anymore. - disabled 16 bit framebuffers for the same reason. As a conseqence all code for rendering without stencil could also be removed.	2013-08-18 15:41:52 +02:00
