gifdec: use truncated width for image manipulation
Some files seem to have an off-by-one error. In most cases, it appears to
be on the image width. Therefore, if the decoded image doesn't fit in the
screen:
- If it is wider than the screen (and the lzw decoding buffer), reject it;
- Otherwise, decode the indicated amount, but only write a truncated amount
to the screen.
Fixes ticket #3538.
