Change the effect of successfully acknowledged packets to bump the 

adaptive throttle by a full MTU. This is consistent with some implementations
of congestion control algorithms and certainly has the effect of opening
the throttle window more quickly after errors. This is especially important
after initial scene load when the number and size of packets is small.
