QGraphicsPixmapItem to QPixmap to QImage and back again!

[bruceariggs]

Yes, it does change the image. I used the save function to output the whole image before and after conversion and the images were different, yet the display never changed.

HOWEVER, I did solve this issue while making optimizations.

I was being silly and converting each tile piece to QImage and back, so I figured, "Why not just do the slow change once on the whole image", so I now do the color change on the entire image just once, instead of millions of times, and now for some reason the color change is showing up.

So... Whatever. Maybe the original problem had something to do with a variable falling out of scope or what-not, but it doesn't matter now, the issue is resolved. =)

Thank you for your help, though.
