Cleaned up getRectsBeingDrawn:count: related code.

Browse Source 
* Removed the exception handler; it's not needed anymore (thanks Ryan).
* Split the if statement and then case into two lines instead of one.
* Took some of the suggestions from the cocoa-dev mailing list:
- Changed code to use normal messaging syntax.
- Provided a category interface to silence the compiler warning on 10.2.
