Description Daniel Rolka

We have the temporary workaround for the issue - Bug 433858, but due to flicking of the Tree widget during redrawing we were not able to fix it in the proper way

NOTE: The flickering was not caused by setting the font but because we removed the setRedraw(*) calls from CSSPropertyFontSWTHandler.setFont(Widget, Font). For Luna we added them back (see bug 433858 comment 34), but those calls need to go away in Mars.

Note that the setRedraw calls that were removed in bug 401633 were not exactly at the same place as the new ones from bug 433858 comment 34 (and bug 435061).

I think this bug belongs to SWT, looks like the need to do the above change in their code.
