You want to override GdkPixbuf's support for Jpeg and thumbnail all JPEG
images using EPeg. It'll beat GdkPixbuf by 5 times or something.
That's because afaik does EPeg use libjpeg in a way that it skips rows
and columns, and that way performs better on both I/O (having to read
less of the original), memory (same reason) and CPU (having to
decompress less, having to scale less or nothing).
Is there any reason not to use epeg in the gdk-pixbuf jpeg loader itself?
