This file tests the wxme image-snip reader against the normal
image-snip reader (ie image-snip-class%'s read method)
It creates a bunch of different image-snip% objects
(the try-perms and below functions)
and then feeds them thru both paths to get two new image snips
(in the beginning of test-wxme-image-snip-reader/proc)
and compares a bunch of properties of them
(the end of that function).
