Hot plugging monitors sounds like *big* pain here.
I don't really see where the pain is coming from, although I agree that
this path is not that appealing. But it would be a valid option if we'd
care about compatibility here.
> This is a really good idea... i'd rather not *completely* trash the old
BeOS accelerant layout as it is working. (even though we aren't abi
compatible with BeOS drivers)
We are not? My memory might fail me here, but I don't remember any issues.
Where do we break it?
> it should be rolled into this as multi-head changes would be a great
time to lay the basework for compositing.
Definitely. Looking at other current graphics driver APIs would certainly
be a good idea.
