Structure the mouse cursor data so that it is easier to switch, and
access it via pointers (still to only 1 instance, now with a less generic name). Restructure the "and" and "or" masks as border and interior masks (where the "and" mask was for the union of the border and the interior). "and" and "or" were only a detail in a not very good implementation, and after fixing that the union was only used to calculate the border at runtime. Use the metric data in more places to clip to active pixels earlier.
