        src/sys/dev/sbus: mgx.c

Log Message:
wait for the engine to go idle before issuing rectfill commands
we get occasional overlap with blit commands if we just wait for fifo slots
needs further investigation, it is possible that not all writes to drawing
engine registers are pipelined and of course we don't have docs
