[OpenJDK 2D-Dev] [8] request for review: 4892259 GIF ImageReader does not call passComplete in IIOReadUpdateListener

[Vadim Pakhnushev]

Hi,

Please review a fix for bug 4892259:
http://bugs.sun.com/view_bug.do?bug_id=4892259
http://cr.openjdk.java.net/~bae/4892259/webrev.00/

Actually GIFImageReader should not call neither passComplete, nor 
passStarted for non-interlaced images in the first place.
So the fix is to check whether the image is interlaced or not and skip 
startPass method entirely in case of interlaced image.
passComplete is called only for interlaced images.

Thanks,
Vadim
