upside down labels

[Stephen Woodbridge]

Regardless of the reason (forced or not) the math that computed the
angle and tries to keep the label right side up is flawed and needs to
be fixed. For any of the upside down labels you could flip them 180
degrees and they would fit in the same space.

On 4.01, I was the only person that reported and complained about it,
but it now seems to be a much more common problem. Maps with upside down
labels do not show mapserver off in its best light. Also the code should
be pretty localized so knowing where to look should not be a problem.

As for localizing a trivial example, that is harder. I'm not sure how to
  identify just the objects required to render a map with the problem
and to extract them into a small set of data files.
