Description
Run attached code sample and follow the next instructions. That is compatibility test, that started to fail, beggining from b12.

Objectives:
This testcase aims at testing the image cursor feature. Typically, the following scenarios are covered -
getBestSize() called with 2 different sizes, one lesser than the platform size and another larger than platform size.
getMaximumColors()
Invalid main image URL and a valid placeholder image is used to see if the given hotspot values are clamped to the size of placeholder image.

User Interaction:
- Hover the mouse on each of the buttons and check if the following cursors are shown 
A bug image on button 19, 19
A giraffe image on button 299, 299
A tiger image on button 290, 290.

A bug and a tiger are not shown for some reason.

Given that we've isolated the problem to just affecting certain types of GIF images, and only when scaling, we are lowering the priority to Major. This will be addressed in 2.2 along with the other GIF image loader bugs.

I verified that this is a regression from 2.0.2, introduced in 2.1.

Note that if the Image is not scaled in the Image constructor, then it works fine. So this is a bug in the GIF loader in the scaling code.

I can verify that the bug still exists. Running the attached test program with -Dprism.verbose=true will print out the AIOOB exception.
