The SYMBOL in OGRFeature contains an angle. However this angle is not used
inside mapserver. The correct behavior is to set the angle in the mapfile
symbol. I will modify mapogr.cpp to accept angle.
Yvain Ballini has provided a test case for this. I will attach it.
Here's the output of ogrinfo on his layer and his layer:
