Description of problem:
eog cannot display transparent png images. The background is checkered
black/gray. I cannot verify that image is 100% conformant PNG
(it is created by gnuplot 4.0), but mozilla and "display" (from
ImageMagic) display it correctly.
I suspect this is fault in one of the libraries since
kview and GQview fail as well.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Save the image from URL to the disk
2.open it in eog
Actual Results: Background is checkered black/gray.
Expected Results: Transparent background

Sample file (transparent png)
This is not a bug, but a feature. Both "eog" (and, for example, the
Gimp) use the checkered black/grey background to display the
transparant part of the picture. In "eog" you can use the preferences
screen to specify what to do with the transparant part of the picture.
