[Interest] I know I'm just being stupid here...

I'm trying to render rotated rich text, and it just keeps clipping on me. I
can't seem to find the magic combination that will expand the clipping region.
The simplest paintEvent():
void VerticalLabel::paintEvent(QPaintEvent*)
{
QPainter painter(this);
painter.rotate(-20);
QTextDocument td;
td.setHtml(text());
td.drawContents(&painter);
}
Slightly more involved paintEvent():
void VerticalLabel::paintEvent(QPaintEvent*)
{
QPainter painter(this);
painter.rotate(-20);
QTextDocument td;
td.setHtml(text());
QAbstractTextDocumentLayout::PaintContext ctx;
ctx.clip = QRectF(0, 0, 100, 400);
td.documentLayout()->draw(&painter, ctx);
}
In both cases, I'm going from this without the rotation:
to this with it:
Question: How do I alter this clipping so the text is visible when it is
vertical? Setting the PaintContext.clip doesn't appear to have any impact no
matter what values I put in it, and Google doesn't have any answers, as far as
I could find.
