slight delay in animated gif loop

[kweto]

Thank you to Jim MacConnell for the interesting "use MOD" suggestion. I
didn't know "MOD" existed.

Unfortunately, "MOD" is not the solution. The documentation explains that:

"If number can be divided evenly into divisor, the expression number mod
divisor is zero."

Which means the currentFrame will get set to 0 (!) at some point in the
loop.

Oddly enough, though, that pesky frame delay is gone! Perhaps my restarting
the computer this morning cleared up an artery or something.

Cheers,
Nicolas Cueto
