Rotates the image in a QPix plug-in area by a number of degrees.
The QPix plug-in area is specified by areaRef. If areaRef is not a valid QPix plug-in area reference, qpx_paramErr is returned.
The number of degrees is specified in the numDegrees parameter. Positive values cause clockwise rotation, while negative values rotate the picture counter-clockwise.
