Some refactoring to make PSwingRepaintManager clearer, nothing too fancy

Issue 74 ; additional minor improvements for better UI responsiveness

Commenting out assert since it doesn't work on all environments

Issue 74 ; minor style and javadoc fixes

Issue 74 ; minor style and javadoc fixes

Trying to get test to pass. Seems to get GC to run

Adding tests for PText

Fixed Issue 74; removed the need to track PSwingCanvas.SwingWrapper instances in the PSwingRepaintManager, making the memory leak a non-issue

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

Changed test name since it was incorrectly referring to PCanvas

Added PSwingCanvas Test for Memory Leak

renamed test since PCanvas was redundant

Fixed a memory leak with PCanvas instances registering themselves with KeyboardFocus and never unregistering themselves. ...

Added a Hierarchy listener so that the inputsources are installeded and uninstalled when a canvas gets added or removed to a parent.

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 # of times finalizers are called.

Issue 74 ; adding PSwingMemoryLeakExample to examples

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.

Issue 74 ; some assertions fail when test case is run as part of a test suite

Issue 74 ; adding unit test for PSwingRepaintManager

Issue 69 ; adding render quality parameter

Simplifying getInverseTransform and making it not call printStackTrace() since it was handling that case anyway. Issue #96 may make this a non-issue anyway.

Issue 53. Removing Test Code that can't be run in Headless mode
