Add support for using images instead of single color pixels?

[Entropy159]

It would be nice to be able to select an image instead of a color, then paint using images on the grid. If you implement this, QPix will become great for Minecraft structure planning like I'm hoping.

That is an interesting idea. If I ever come back to work on QPix, I might consider implementing that, but QPix is kinda abandonware at this point. Feel free to fork the repo and add that functionality yourself though.
