Currently src/drivers/OpenGL/Fl_OpenGL_Graphics_Driver.cxx wouldn't contribute any code to the lib, but it is kept for future extensions. This file is no longer compiled (see src/CMakeLists.txt and src/Makefile). Tested (only) under Windows and Linux. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.4@12381 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
