Draw contour labels in the orientation from lower contour to higher contour
As a standard contour labels should be drawn in an orientation so they are readable from lower to higher. At the moment contour labels are always drawn that they are readable page up. This makes it hard to see straight away, where on the plan are the high points and where are the low points. Architects might disagree, as it doesn't look as nice, if the labels are upside down in some places, but I'm pretty sure it is more useful, when reading a plan.
It should be possible from the TIN to determine, which side is up, so the contour labels can be placewd accordingly.
