New Revision: 1812764
URL: http://svn.apache.org/viewvc?rev=1812764&view=rev
Log:
Make some new variations on the "prepareForText" methods in GraphicsUtilities
for use in other places in the code. Also add a method to set the font
rendering hints. And methods to set anti-aliasing on and off.
All these are common operations during drawing that deserve common code
treatment for consistency and brevity.
