Description
This patch adds a fourth gps-trace coloring mode which is very useful. Additional to "constant color", "velocity" and "dilution of precision" the option "direction" is created.
Coloring the traces according to the direction of each segment especially helps to assign traces to each side of a street separately.

The adjusted colors look nice. Actually I thought about changing the hsv colors myself a bit, but then I rather kept it simple. However I think the x*x*x transition function is a bit strong, what about using x*x or x1.5 ?
Make sure to adjust line 47 in DrawingPreference.java !

The problem is that yellow is dominated by green and red. The strong transition is an easy way to ensure, that all 4 colors appear in a balanced way.
