Usage:
to an executive. This makes a button labeled "Mag" at the top of the screen. Click it with the left button to get a small, medium, or large magnifier, depending on the mouse button used. Click the right mouse button to get rid of the current magnifier.
Other sizes of magnifiers may be created with the executive, i.e.,
CreateButton M1 ← Magnifier.DoIt[60, 30]
makes a command tool button for a very small magnifier.
Try Magnifier.dotStyle ← b1 for a little different display.
Rough spots:
The screen is frozen while the magnifier is active.
