Lines with truetype font symbols

[Håvard Tveite]

I am using short straight lines of truetype font symbols to
place oriented symbols on the map at specific locations.
In Mapserver 4.10 this worked OK, but in 5.0b5 it gives the
expected results for lines going from west to east (larger
x-coordinate for the end than the start of the line), but
the opposite orientation of the symbol for lines that go
from east to west (larger x-coordinate for the start than
the end of the line).
Is this expected behaviour?

A map file that illustrates the problem:
