Native resources (bitmaps, matrices, paints, shaders) are shared when display lists
are used, and a refcounting system is in place to take care of disposing when all
clients are finished with them. But the cache where these refcounts are tracked is
not enabled when the Open GL renderer is not being used. This results in the native
destructors not being called, and the resources are leaked.
