Hi,

The grid system probably does make life easier.  The only reason I found it a
little strange, was because I used many grabbers like this on the Amiga, when I
was working with the AMOS language, and I used similar methods to create a
sprite/bob bank.

Your original method is probably much better... I'm just strange, and draw all
my little images in little white boxes of the right size :))
