Removing unused imports

fixed possible bug with double[].toString() preferred way of doing this is to use the Arrays.toString() method

Marked the static instances as final

Marked ALL_MODIFIERS_MASK as final

Added back in check for modifiers applying to input events. Turns out some of the examples expect this behaviour (NavigationExample being one).

Change path back to private scope. Accident caused while trying to figure out a way of unit testing the generated path.

Removed some unnecessary imports from PCanvas

Refactored mousePressed and mouseReleased so that code common to each is now in a helper method. Net result is a much lower cyclomatic complexity for each.

Adding more tests and adding tests for PDebug

Unit tests

Added tests for PBasicInputEventHandler

Added getInputEventListeners to PCanvas and PNode making them return an array of PInputEventListener objects. This makes it fall inline with the other listeners inherited from JComponent and it also makes listener methods testable.

Reverted override of createInverse in PAffineTransform since the fact that it didn't throw anything was being overlooked in Hudson, but honoured in Eclipse

Removing some calls to printStackTrace(), replacing them with appropriate responses Issue 101

Fixing bug with PImage being run in Headless Mode

Unit Testing for PImage and removed a little cruft

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

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 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.
