Neil Toronto faa9ae72fd Remove dependence on libgtkgl; fix indirect rendering problem ... The right way to render to pixmaps is to create a GLX pixmap wrapper and render to *that*. Almost nobody does this - including libgtkgl - and it's almost never a problem. But it causes crashes on my system in indirect rendering mode. This commit changes three things. 1. OpenGL on Linux no longer requires libgtkgl, only libGL, which comes preinstalled on many (most? almost all?) systems. 2. Rendering to pixmaps is done properly, via a GLX pixmap wrapper. 3. Direct rendering is done whenever possible, even for pixmaps. original commit: c601b82f04586b686583107b80aceef4e8606ae1		2014-10-01 22:51:03 -04:00
