red-green-blue-repeat-2.gif

Open the attached files:

1. red-green-blue-repeat-1.gif: loopCount == 1. The image should be animated only once.
2. red-green-blue-repeat-2.gif: loopCount == 2. The image should be animated twice.

RESULT: All images are animated one extra iteration than what it should do.

NOTICE: This regression affects the case where loopCount == 1 or the case when it is missing from the file. For the cases loopCount > 1, the bug did exist before this regression.
