            Description

            When a PDF document is loaded that contains images a relatively significant amount of time is spent parsing the image data. When the image is being parsed it blocks the main content thread and as a result the perception of load time is greatly increased even if there was text or other shapes that could be immediately been painted.

            I would like to introduce an image proxy that would differ image loading until the image actually needs to be painted or processed by a separate consumer thread. The Shapes class already has a paint observer setup for incremental painting, this same mechanism could be used to queue a repaint of a page when the images becomes available.
