[Qt-interest] Force QTextDocument to use outline fonts?

[Chris Meyer]

I have a QTextDocument drawing into a QGLWidget (via the
drawBackground method of a QGraphicsScene).

When I render the QTextDocument on Windows using the drawContents
method, I get bitmapped fonts when the font size is below 24pt.

Is there a way to force QTextDocument to use outline fonts instead of
bitmap fonts?

Using Qt 4.6.2.
