vp

pointer to ViewPort structure

This function will return sometime after the beam gets beyond the bottom of the viewport. Depending on the multitasking load of the system, the actual beam position may be different than what would be expected in a lightly loaded system.

Horrors! This function currently busy waits waiting for the beam to get to the right place. It should use the copper interrupt to trigger and send signals like WaitTOF does.
