2 | * GTK UI -- egl opengl code. | |
3 | * | |
4 | * Note that gtk 3.16+ (released 2015-03-23) has a GtkGLArea widget, | |
5 | * which is GtkDrawingArea like widget with opengl rendering support. | |
6 | * | |
7 | * This code handles opengl support on older gtk versions, using egl | |
8 | * to get a opengl context for the X11 window. | |
