This code adds threaded processing of a batch of images. It uses the QtConcurrent implementations to call a function repeteadly using MAX_THREADS (Qt gets that for us) and returns a list of it. This call is blocking, so while the pixmaps are being scaled in threads, it will wait for all scalling to be done.
