// which will start to replay it as fast as possible, rendering <prof> frames
// for each gametic.
//
// Notes:
//  * The demos should be recorded with demorec_diffs set to 0, so that the
//    game state updates are actually computed.
//  * Currently, the profiling can only be aborted on SDL 1.2 builds by
//    pressing any key.
//  * With <prof> greater than 1, interpolation should be calculated properly,
//    though this has not been verified by looking at the frames.
//  * When testing whether a change in the source has an effect on performance,
//    the variance of the run times MUST be taken into account (that is, the
//    replaying must be performed multiple times for the old and new versions,
//    etc.)
