"minfeaturesize auto" causes labels to never be drawn

[dougrenwick]

Issue: "minfeaturesize auto" is documented as causing labels to appear only when their containing polygon is larger than the label. In my tests, it causes labels to never be displayed.

Demonstrations:

Default label handling: ​http://maps.hostgis.com/gregor/mww_example/ ​http://maps.hostgis.com/gregor/mww_example/mapfile.txt

LABEL

COLOR 0 0 0 TYPE truetype FONT "Arial" SIZE 9 POSITION cc

END

Minfeaturesize 36: ​http://maps.hostgis.com/gregor/mww_example3/ ​http://maps.hostgis.com/gregor/mww_example3/mapfile.txt

LABEL

COLOR 0 0 0 TYPE truetype FONT "Arial" SIZE 9 POSITION cc MINFEATURESIZE 36

END

In this case, there are still several polygons (note the northeast quad of the map) which lack labels though they're above the minimum size and labels would not collide. That's probably beyond the scope of this submission, but is still interesting and my employer considers it "bug like"

Minfeaturesize auto: ​http://maps.hostgis.com/gregor/mww_example2/ ​http://maps.hostgis.com/gregor/mww_example2/mapfile.txt

LABEL

COLOR 0 0 0 TYPE truetype FONT "Arial" SIZE 9 POSITION cc MINFEATURESIZE auto

END

Note that labels are never displayed. This is also the case even if "FORCE true" is set.

Are we sure the labels simply aren't too big?

Nevermind, I can recreate (I'm a moron)...

Turns out that this feature never worked. Fixed in r6777.
