- setTextWidth() returns without a signal when the width does not
change, which is also the case on every load of a text without one.
- Say why IndependentTextItem::textWidth()/setTextWidth() hide the
non-virtual QGraphicsTextItem functions, and what that means for code
holding a base pointer.
- The fixture no longer carries a /tmp path from the machine it was
made on.

A free text (IndependentTextItem) gets a textWidth property: -1 is the
automatic width (one line, or lines broken by hand, as today); a
positive width makes the text wrap between words. Its top-left corner
stays in place. The property is what a spin box and resize handles will
set in follow-up changes.
File format: the width is saved as text_width on <input>, only when one
is set, so a project without widths is saved byte-identical
(tst_resaveunchanged). An older QElectroTech ignores the attribute and
shows the text on one line, with no load error.
DiagramTextItem::setHtml() no longer widens a centred or right-aligned
rich text to idealWidth() + 40 when the text has a width of its own;
with the automatic width it still does.
Test: tst_freetextwidth (--resave keeps the width only where set,
--export-svg draws the text wrapped).
