1. RE: large bitmap
Tone, I have just now sent an update of my dib library to RDS. The only
adjustments made in this release were adding 2 new demos. These demos
show zooming and displaying only part of a bitmap (in this case a dib).
If your computer has enough memory (ram) then this will not be a problem
but to load 100mb might take some time..

Someone else said the same thing but I thought I fixed all that
before... Perhaps I used an old version of the library for this release.
nevermind i'll fix all that right now.
