Several fixes for wxAffineMatrix2D transformations.

Browse Source 
Correct errors in TransformPoint() and TransformDistance().

Change Rotate() to interpret positive angles as rotating clockwise, for
consistency with wxGraphicsContext::Rotate().

Improve the unit test to verify that all the transformations work correctly.

Closes #14334.
