Regions
Up to 8 regions can be defined for a mask. They can be numbered 1- 8.
They can appear in any order in the .msk file. The numbering of the
regions must go from top to bottom, left to right.
An Automask file contains two special regions: the region "glued" to the
top of the display, and the region that is "glued" to the bottom. The top
region is indicated by y- values of "MAX" for the first and last points. The
bottom region is indicated by y- values of "MIN" for the first and last
points.
The top region must be the lowest numbered region in the file. The
bottom region must be the highest numbered region in the file.
