This resource demonstrates the basics of the CheckRadio CDEF.
This CDEF uses a resource of type 'cicn' with all of the various
control states, arranged in a 3x3 grid. Presently, the CDEF assumes
that each piece of the 'cicn' resources will be 16x16 pixels, for a total
size of 48x48 pixels for the whole icon.

The CNTL resource should contain the following items:
• The size of the Rect the control will occupy (starting at 0, 0)
• The initial value & visibility of the control
• The maximum and minimum values
• The ProcID of the CDEF. This is the ResID of the CDEF * 16
• The ResID of the 'cicn' resource specified in RefCon
• The title of the control for the text label

The CDEF handles black and white. If you look at the sample
'cicn' resources, you'll see that each of them has black and
white parts that correspond to the fancy color ones. The black
and white parts should be identical to traditional Macintosh
controls.
