Hello All,
Please review the following fix.

Issue: Wrong resolution variant image is used in Tray Icon.
Fix : Applying the device transform to graphics object to select the
correct image.
The image could be cropped on Linux because the high resolution
icon which size is bigger that the original image is drawn to the
buffered image with un-scaled size curW x CurH.
It is better to get a resolution variant from the multi-resolution
image, draw it to a buffered image with the same scaled size and then
draw the buffered image to the paint graphics using original size:
-------
Image resolutionVariant = ((MultiResolutionImage)
image).getResolutionVariant(scaleX * curW, scaleY * curH);
BufferedImage bufImage = new BufferedImage(scaleX * curW, scaleY *
curH, BufferedImage.TYPE_INT_ARGB);
// ...
gr.drawImage(image, 0, 0, scaleX * curW, scaleY * curH, observer);
// ...
g.drawImage(bufImage, 0, 0, curW, curH, observer); // non scaled
width and height
-------
By the way, is the buffered image necessary in this case? Is it
possible to draw the image directly to the paint graphics?
-------
g.drawImage(image, 0, 0, curW, curH, null);
-------
Thanks,
Alexandr.
