JPEG image format and the new callout capabilites in LPub (plus PLI background
color non-white which I just fixed) are incompatible with JPEG because when you
pack images together that are rendered with the same background color, not all
the backgrounds look *exactly* the same.
I'm going to add PNG support to LPub for building instructions and want to
eliminate JPEG and BITMAP capabilities. This will simplify things in a *lot*
of places in LPup. Those of us who authored books for Syngress using LPub used
bitmap format because it was loss-less. For web publishing, JPEG is typically
used because of reduced file size.
PNG provides lossless compressed images. Rather than having to support all
three formats bitmap, JPEG and PNG, I only want to support PNG.
Any objections?
