There are a lot of tasks in OOo that only require PNGs in preview quality.
Currently previews in OOo are done by loading the entire image and then scaling
it down by using selected pixels of the full image. By using a preview image
that is just big enough but smaller than the complete image there would be these
benefits:
- less memory usage
- by not needing the memory for the full blown images
- increased speed by
- no need to decompress the whole file for interlaced PNGs
- no need to paint every pixel
- no need to unfilter a scanline if the next line
requests only a "None" or "Sub" filter
- less work for Image->UniqueHash operations
