I just worry what happens to machines without screens but that can have
gfx cards added. By the current level of thought behind these variables
a divide by zero is inevitable.

It also triggers my gut feeling of "this is the wrong way to crack the nut"

Nothing, but these variables seem little thought out and seem to be being
rushed into use for one use case (opie backgrounds).

And if it is neccessary then it should be the "correct" information, like
for spitz the screen is 480x640 by default. Deal with it in packages that
wish to use rotation correctly. Not just this value makes it easy for my
magic background generator.

Maybe a MACHINE_DEFAULT_ROTATION is also needed.
