6: To get higher resolutions on the Desktop, we intercept the VDI/Line-A calls and set elements
7: in their structures to the higher width/height/cel/planes. We need to intercept the initial Line-A
8: call(which we force into the TOS on boot-up) and also the init calls to the VDI.
9: As we intercept the VDI calls, this is a good point to pass them on to the accelerated native
10: PC functions if we need to - this improves drawing speed far greater than any ST software
11: accelerator.
