Orientation guide for existing Blitz users

The import option is really cool, and does most of the work.
Unfortunately, my code relyies heavily in the use of tcp streams and lots of 2d graphics operations that don't seem to have an equivalent in BM (MaskImage, for instance).

I am not saying that it does not work. On the contrary, the importer is a valuable tool but, unfortunately, direct conversion is not possible.

Thanks
