Peter Cherna (in charge of Intuition) asked me to correct/append
my statement that we do not support overscan screens under 1.3.

The 1.3 OS does not provide full support for overscan screens.

However, besides the solution I listed above (which I feel is safe
and perfectly suitable for the stated application), there is is also
Jim Mackraz's 1988 Devcon article/example on Overscan where Jim provides
some more complex but relatively safe methods for creating and using
overscan screens under 1.3 with full mouse travel.
