(just in case: Ian somehow dragged me into this - i had not installed any games nor played kbounce before ;-)</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Not extremely related to your patch. But people were talking about QGraphicsScene becoming obsolete in QT5.
As this game is going to be ported soon, I'm afraid of future headaches. What do you know about it?</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I don't think so - it's in the Qt5::Widgets component, not deprecated and afair serves as backend for QML
Where did you pick that?</pre>

Is it signaling that the walls need to be repainted? If so, I believe we can provide it a better name.</pre>

The patch looks bigger than it is, i had to partially fix coding style in order to read through it, sorry.
The MAJOR issue with the code is that it causes recursions on the eventloop by altering graphicsitems from the paint() call ("setPixmap()"), so i scrathced that.
It seems a cause was that a full repaint was forced by setting some invisible fullsize pixmap item, while the only requirement for this was actually when finishing a wall - so i replaced that with an explicit full update call on occasion.
Also all non-raster graphicssystems HATE QPixmap::fill(Qt::transparent) causing a 24bit -> 32bit change and it's esp. bad on the nvidia driver.
So i reduced that (and allocation) by re-using the old (ARGB) pixmap on a 64x64 alignment.
Ian, you might esp. check that impact on OSX.
Last I cached the sprites, seemed reducing cpu on permanent paint (but i didn't really measure)
I'll also mark & comment the actual changes in the diff.</pre>
