    Fix detection of OpenGL 3.3 core GL_ARB_timer_query.
    
    Some systems (notably macOS) will not allow enumeration of an extension that has been promoted to core 
OpenGL for context in use. This change assumes that GL_ARB_timer_query is available on OpenGL 3.3+.
    
    I could not find definitive information on whether GL_ARB_debug_output or GL_KHR_debug have been added to 
core. Other extensions in use were addressed by https://gitlab.gnome.org/GNOME/gtk/merge_requests/1422 .
