Returns a transform that rotates coordinates by the specified number of quadrants. This operation is equivalent to calling:

     AffineTransform.getRotateInstance(numquadrants * Math.PI / 2.0);

Rotating by a positive number of quadrants rotates points on the positive X axis toward the positive Y axis.

Parameters:

numquadrants the number of 90 degree arcs to rotate by

Returns: an AffineTransform object that rotates coordinates by the specified number of quadrants.
