Subject: [PATCH] glretrace: Flush outstanding requests when waiting for user
 input.

This helps make "apitrace replay -sb" work in cases where the driver
really only exposes double-buffered rendering, (so a flush is required
to make anything appear if the trace doesn't include a final
SwapBuffers).
