Well, the reason I started this was because I wanted some code to stick
into a cgi script that was at the backend of some J2ME database driven
stuff (that processed JPEGs into PNGs - as PNG is the default format for
mobiles).

I wanted some code to shrink the size of the PNGs - as this environment is
so slow and it's still about 0.1p per KB of data delivered.

I got that bit to work - the rest is just intellectual enquiry to be honest.
