Description of Problem:

Both HorizontalResolution and VerticalResolution of an 
System.Drawing.Image return 0 when the image is a png

Note that this does not happen with a jpg (bug already solved : 
https://bugzilla.novell.com/show_bug.cgi?id=MONO68117)

Steps to reproduce the problem:
1. Load a png image using "Bitmap.FromFile("/path/to/a/nice/image.png")"
(System.Drawing)
2. Read properties VerticalResolution and HorizontalResolution : they should be
zero !


Actual Results:

Resolution is 0.

Expected Results:

The resolution should not be 0...

How often does this happen? 

Always.

Additional Information:

As written above the bug has been corrected for jpg
(https://bugzilla.novell.com/show_bug.cgi?id=MONO68117) but seems that it is
still there with png.
