Some Unit Tests for PInputEvent

Adding tests for PText

Adding tests for PText and making it return empty string by default rather than null. More inline with JTextField

renamed test since PCanvas was redundant

Added Memory Leak Test for PCanvas, should demonstrate the memory leak installInputSources has

Fixed Issue 100; Plastered PInputEventFilter with Unit Tests and then made it consider the masks conditionally. ...

andMask if it's non-zero
notMask if it's non-zero
orMask if it's not ALL_MODIFIERS (I can't think of a case where you might want to say, "Only allow events as long as they have a modifier, I don't care which one")

Adding some PInputEventFilter tests.

Removed unnecessary call to getFullBounds in test. Probably just a hangover from a past test.

Fixed Issue 91; deprecated repaintFromlayer(PBounds, PNode) in favor of the more specific repaintFromlayer(PBounds, PLayer) making it impossible to accidentally pass a camera say to this method.

Fixed Issue 96; Made PAffineTransform throw PAffineTransformException (a subclass of RuntimeException) whenever a non-invertible transform is encountered. ...

In the process, I removed 2 printStackTrace calls from the code base.

Fixed Issue 92; make it check for empty stack before popping the cursor

Fixed Issue 94; made removeLayer(PLayer) "fail" silently. Also added some additional tests and refactoring. Sorry for such a large commit, I'd try to split it up, but it's hard to tell what's safe to leave out and what's not. I know that the whole together unit tests fine. I have to remember to checkin more frequently.

Some tests for PDragEventHandler

Adding some preliminary tests for PInputEvent

Added some trivial tests for PPanEventHandler and added come accesors to it for maxAutoPanSpeed and minAutoPanSpeed. ...

Also, cleaned up test for PAffineTransform.

Added some tests for PAffineTransform

Moved mockListener out of methods and into the setUp. it's common enough to warrant it.

Slight modification to MockPCamera for extensibility.

Tests for PRoot

Added more tests for PCameraTest and removed an errant ImageIO.write in PNode

Added test for PDebug.debugBounds enabled

Added accessors for render quality on PCanvas (Issue 93) , and also wrote more tests to confirm that Issue 87 is fixed.

Added some move tests to PCanvas

made toImage(int, int, Paint) return an image of the size requested. Since it seems that the resizing is already done in PNode.paint it was just a matter of deleting the resize code. ...

Also, I've added 3 tests to PNodeTest that try and confirm the behavior.

Added some tests for PInputManagerTest. Difficult to create a mock PickPath so the mouse specific code is largely untested.

Added some more tests for PCamera and broke MockPropertyChangeListener out into its own top level class. Also, cleared up some wording in comments.

Adding some unit test to PLayer, 98.7% instruction coverage booya.

Modified PNode so that it retained public interface clirr. I'll run that from now on. Thanks, and sorry heuermh

Pushed up UnitTest Instruction Coverate of PNode up to 90.1% and reorganized PNode slightly so that it was easier to test position.
