I  think loading  shouldn't be  _fully_  based on  showing. Yes,  it's
better to load images from current page first, but then start a thread
that will preload other images in background.
Maybe you meant it here... =)

We  could use  mipmapping for zooming.  Isn't  it too  heavy for  that
purpose? I'm  thinking over it's  realisation in krita's  paint device
right now. You could use some code from that in the future...
