This is the first of two commits that completely turn the rendering code on it's head. This change set decouples the guest's capture rate from the host's render rate for both cursor and frame updates. This helps prevent the host application from stalling when waiting for frame draws when all it want's to do is send cursor updates. * Breaks OpenGL-Basic for now
