MGH_EXAMPLE_POLYFILL
Name
MGH_EXAMPLE_POLYFILL
Purpose
Testing various methods of polygon filling.
This routine has been used to compare the behaviour of various
filling methods when the polygon vertices move out of the positive
quarter plane, see
http://groups.google.com/groups?hl=en&threadm=000c01c14c6e%243388ee50%24d938a8c0%40Hadfield&rnum=1&prev=/groups%3Fas_epq%3Dpolygon%2520filling%2520oddities%26as_ugroup%3Dcomp.lang.idl-pvwave
Note that different filling routines do *not* give identical
results. They use subtly different assumptions about the position of
pixels and some of them (POLYFILLV) do suspect things with the
polygon vertex positions. I have other test routines that explore
these issues.
