fl_font() sets the "current font" used for drawing
which fl_measure() says it needs in the docs.
textfont() and textsize() don't affect the current font
used for drawing, they just set the widget's text font.

Not sure I understand what you mean by "adding a dummy Fl_Ouput"?
Do you mean the call to Fl_Output::draw()?
If so, would make sense to do that /last/, after you
do your fl_measure() and resize() calculations.
It doesn't make sense to call Fl_Output::draw() first
if you're just going to resize the widget later,
which will cause another redraw.. drawing the widget
twice instead of once..
Keep in mind if you don't call Fl_Output::draw(),
the widget won't draw at all because your draw()
routine is replacing it.
