gtk: add opengl support, using egl
This adds opengl rendering support to the gtk ui, using egl. It's off by default for now, use 'qemu -display gtk,gl=on' to play with this. Note that gtk got native opengl support with release 3.16. There most likely will be a separate implementation for 3.16+, using the native gtk opengl support. This patch covers older versions (and for the time being 3.16 too, hopefully without rendering quirks). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
