Hi, Randall!

Did I say "max-length"? Doh.

The attributes are:
min_width, min_height: minimum size (can't be shrinked to less than
max_width, max_height: maximum size (doesn't grow bigger than that)
def_width, def_height: default size (starts up with this size)

Due to technical limitations of wx, def_width/height can't be different
from min_width/height and is thus ignored.

Yes, indeed. Actually, the anomality is that all fields are of undefined
length: even unbound fields can (and usually would) have a datatype and
length defined.

I tend to recommend to not put too much work into migration. I have no
idea how many gfd's are out there which ever would be migrated, but I
don't think there are tons of them.
