Change History (most recent first): 6/2003 MK Updated for ProjectBuilder 08/2000 JM Carbonized, non-Carbon code is commented out for demonstration purposes. 7/14/1999 KG Updated for Metrowerks Codewarror Pro 2.1 8/27/92 BS added a direction parameter to the end. It will rotate in the direction you specify. ALSO fixed some LAME bugs, such as the rotate routine did not preserve the current port,and it also did not dispose of a temporary bitmap it used.
