[PyQt] QGrahics / textItemSize

[Philippe Crave]

Thanks for testing !

I attach a new code with Arial (maybe you're under windows) and a new png.
this time, I also draw a rectangle. 200x40px, red.

you can check that the scene produced my the pyqt code gives a rectangle
like the one in the png. I did it in inkscape. a 200x40px red rect.

but for the font, "hello 1" is too big. "hello 2" seems to be of similar
size. but it was scale.
I attach the .svg too.
in the svg (and the png), i wrote "hello" in arial/40

why should I scale the text (with a ratio of .75) to get a correct size ?
