Add option to Image class to ignore embedded DPI resolution when rendering

[mike-ward]

Images with embedded DPI resolution (DPIx, DPIy) render smaller/larger than desired when the image control container is unbounded. A property to control this behavior would be much appreciated.

Example:

<Image 
    Source="{Binding HttpSource}"
    IgnoreEmbeddedDPI="True" />

How about make it as the attache property?

What I really would like is to not have to even consider it. Here's an image rendered in WPF (Stretch=Uniform, StretchDireciton=downonly)

And here's a same thing using AvaloniaUI with same stretch properties.

Avalonia's behavior is the one I want.

I would say images with embedded DPI information render as they instruct to do so (and file a bug on AvaloniaUI for ignoring it). If you want special treatment like ignoring DPI, color profile or orientation, you should do the extra work.

@miloush I would say otherwise. The aspect ratio of the image is wrong and the image looks terrible. And for the record, I did do the extra work and still ran into to issues which is what prompted this bug report. Finally, I would like to thank you for your supportive and encouraging comments. It's kind and thoughtful comments like yours that keep the community open and welcoming.
