- glimagesink needs to be able to resize the viewport on aspect ratio changes resulting from either caps changes or 3d output mode changes. - Performing a glViewport outside the GstGLWindow::resize callback will not have the winsys' stack of viewports required to correctly place the output frame. Provide a function to request a resize on the next draw event from the winsys. Also track size changes inside the base GstGLWindow class rather than in each subclass. https://bugzilla.gnome.org/show_bug.cgi?id=755111
