/**
* I decorate some PopplerBufferedRenderer that produces NSImageReps
* and draw these bitmaps directly to the screen.
*
* I use a very simple caching mechanism to improve performance. I remember
* the last rendered image together with the page index, source box and the
* scale factor. If you ask me subsequently to render the same page with the
* same scale factor and the same source box I will use the cached image instead
* of rendering it again.
