Minimal program to reproduce the bug

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.3)
Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)

After create an Image instance (new Image(100, 100)), and setting image
resolution
to certain dpis (different to 96), if and instance of Graphics is created based
con that Image instance (Graphic.FromImage(instance)), the Graphics instance
return wrong dpi value (instead of taking dpi from Image instance is defaulting
to 96)

Reproducible: Always

Steps to Reproduce:
1. Create an Instance of Image with img = new Image(100, 100)
2. Set the resolution to a value different to 96 (img.SetResolution(100, 100))
3. Create an instance of a Graphic with gr = Graphic.FromImage(img);
4. Verify that gr.DpiX and gr.DpiY are different to img.HorizontalResolution
and img.VerticalResolution respectively.
Actual Results:  
Wrong dpi value for the Graphic object (not equal to the resolution of the
Image object)

Expected Results:  
Same value of the Dpi for the Graphic object and the Image object
