[PATCH] Get rid of QPainter warnings

[Rafael Fernández López]

Hi Germain,

Actually, the test is wrong from my understanding. You cannot start the 
painter there and then do the render on the pixmap.

Ideally, you should what the attached patch does, or if you create the 
QPainter on the beginning perform an end() and after rendering, a begin().

As said here:
http://doc.trolltech.com/4.3/qwidget.html#render

## QUOTE ##
Note: Make sure to call QPainter::end() for the given target's active painter 
(if any) before rendering. For example:
 QPainter painter(this);
 ...
 painter.end();
 myWidget->render(this);
## !QUOTE ##

The attached file does the same, but making this rule be obeyed.


Bye,
Rafael Fernández López
