This patch is to change the inheritance of GstVaapiDisplay to GstObject, instead of GstVaapiMiniObject. In this way we can use all the available infrastructure for GObject/GstObject such as GstTracer, GIR, etc. In addition, a new debug category for GstVaapiDisplay is created to make it easier to trace debug messages. It is named "vaapidisplay" and it transverse all the VA display backends (DRM, GLX, EGL, Wayland, ...) This patch is a step forward to expose GstVaapiDisplay for users in a future library. https://bugzilla.gnome.org/show_bug.cgi?id=768266 Signed-off-by: Víctor Manuel Jáquez Leal <victorx.jaquez@intel.com>
