#301 Saving picture with non-full ACTIVEAREA saves all black pic

[David Costanzo]

The 3dmovie.lgo example creates an animated GIF of a flowerbox folding. However, in FMSLogo 6.16.1, it produces a black GIF.

This bug was reported to me by Michael Malin. It was originally reported in the Google Groups here:

How Reproducible:
Every Time

Steps to Reproduce:
1) Open "Examples/3d/3dmovie.lgo"
2) After it finishes, open Examples/3d/3dmovie.gif with a GIF viewer.

What Happen:
The image is all black.

Expected Result:
The image is an animated GIF of a box closing.

The problem extends beyond 3dmovie.lgo. Saving any image when the active area is not full-sized produces an all-black picture. I am increasing the priority of this because it's such a common use-case.

Updating the title to reflect the true scope of the bug.

I have submitted a fix for this. It will be available in FMSLogo 6.17.0.
