TextBox now supports the 'direction', 'lineThrough', 'textDecoration', and 'tabStops' styles, and the "start" and "end" values of the 'textAlign' style.
The default value of 'textAlign' for Gumbo components is now "start" rather than "left". This is currently done in the type selectors for TextGraphicElement and TextView rather than in the 'global' selector, to avoid changing the default for Halo components.
QE Notes: New functionality to test.
Doc Notes: None
