When test runs a Frame which contains a yellow button labeled
"Drag ME!" and a RED Panel will appear.
1. Click on the button and drag it to the red panel while holding
the "CTRL" key on the keyboard.
2. When the mouse enters the red panel during the drag, the panel
should turn yellow.
On systems that supports pictured drag, the image under the
drag-cursor should appear.
"Image under drag-cursor" is a translucent blue rectangle + red
circle and includes an anchor that is shifted from top-left
corner of the picture to inside the picture to 10pt
in both dimensions.
On Windows, the image under the cursor would be visible ONLY over
drop targets with activated extended D'n'D support.
It means the image may not be displayed when dragging over some
windows, this is not an error.
The image should be displayed when dragging over the red/yellow panel.
3. Release the mouse button.
The panel should turn red again and a yellow button labeled
"Drag ME!" should appear inside the panel. You should be able
to repeat this operation multiple times.
If above is true press PASS, else press FAIL.
