RibbonWindow icon is blurry

[chdft]

With the current dev-version of Fluent ribbon, the icon of the RibbonWindow is blurry again. A similar behavior was already observed and fixed in #50 and #63, however this time, the blurry icon is not stretched. As you can see in the following image, all icons are 16px tall (as expected).

(from left to right: Windows Explorer (correctly rendered icon); .Net 4.0; .Net 4.5)

Judging based on the color of the pixels representing the border, it looks like WPF is trying to move the icon half a pixel upwards. Normally this should be prevented by setting SnapsToDevicePixels="True" - as is already done. Maybe setting the Margin="4,1,0,0" instead of Margin="4,0,0,0" helps, like in #63.
I'm currently unable to test this potential fix myself, since I'm still stuck with VS2013 :/

This behavior is reproducible using the Fluent.Test application. (I used the build from appveyor)

Environment

• Fluent.Ribbon v5.0.0-dev0430
• Theme Office 2013 (only available)
• Windows 7 and 10 1607 (Build 14393.10)
• .NET Framework 4.0 and 4.5
• DPI-Settings/Scaling 96ppi/100%

Will have a look at this.

Changing the margin fixes the issue. Somethings WPF is a bitch...
