"""
This is a generic paged view widget.
Its main design goal is to display the pages of a PDF document, but it can
display any set of images or pages, originating from different documents.
Every page is represented by a Page instance, which encompasses all logic
for the document type, i.e. drawing etc.
Pages are managed by a PageLayout.
A PageLayout can be set to a View so the pages are displayed.
The images from a PDF, SVG of possibly other document are cached, and rendering
is tile-based, to support zooming in at great detail. Also a magnifier is
available, which by default pops up at Ctrl+click.
Because the qpageview is built on Qt, we use the Qt convention
to have camelCase method names and CamelCase class names.
