Force swap buffers when re-creating the buffers
The SwapResult provides a way to signal when the buffers are no longer
adequate and need to be re-allocated. Currently the surfaceless
implementation of the GpuBrowserCompositorOutputSurface will re-allocate
the buffers, however it doesn't swap again. Since the previous buffer
was rejected the display is showing an old frame.
