Synchronize SV buffers with main window when config changes

When the main window gets a configuration change, the new buffer for the
SV will get applied in the same transaction as the main window. This
will allow apps to implement seamless rotation without a frame or more
of black where the SV was resized, but the buffer was not yet updated.

This also includes an optimization where if only SV change occurs, but
there was no request from WMS to report drawing, VRI can apply the
transaction immediately without reporting to WMS.

Test: SV with seamless rotation enabled
