PHtmlView: Making it only attempt to fitHeight when width > 0. Otherwise bad mojo.

Made test use actual height of html node instead of a hard coded value.

PHtmlView - removed the JFrame.pack() hack. I feel better now.

Broke apart tests of PHtmlView so that 1 test = 1 behaviour.

Major reworking to PHtmlView so that it calculates its bounds correctly based on a fixed width and a variable height. Will make it more generic later.

Issue 111 ; adding example to demonstrate text offset bounds problem with PHtmlView

Made PHtmlView text follow node bounds. Became apparent when setting a background paint color.

Accidental IO remnant during testing.

Added test for PHtmlViewTest that checks for paint covering the entire bounds.

Resolved Issue 32 using steveonjava's code. ...

Issue 71; Made clicked on PStyledText nodes retain their scale if they were not new when clicked.

Fixed bug causing PFrame not to display by default.
