title: How small can the Text in a QGraphicsScene get?
body: <p>I'm trying to implement my own <code>QGraphicsItem</code>s to display in a <code>QGraphicsScene</code>. One advantage of this is, that I can keep the positions and sizes of my business objects, without having to convert between them and the display coordinate system.</p>
  
  <p>But: Unfortunately the sizes are small, like 0.5 (meters). This is not a problem with the <code>QPolygon</code>s, but when I want to display text at half the size of the objects, below a point or pixel size of 0.5, nothing gets displayed.</p>
  
  <p>I got around that somewhat by having the labels separately created in the scene as <code>QSimpleTextItem</code>s and scaling them afterwards, but I don't want that kind of separation.</p>
  
  <p>Am I missing something? Like a way to scale everything times 100 behind the scenes?</p>
  
  <p>Update:</p>
  
  <p>I now also tried scaling the <code>QPainter</code> object up, so that I can use more "normal" font sizes, but it seems this does not change the behaviour.</p>
  
  <p>Scaling everything by <code>100</code> and then setting the font (point) size to <code>0.2 * 100</code>, does also not show the labels.</p>
