Fix window not staying in place when changing images

[Ruben2776]

Currently the window is forced to center, to avoid gradually losing center position.

This would be nice to fix, so that you could drag the application around and change images, while still having it the window resizing.

Like how JPEGView works (which this application is heavily inspired by).

Resizing is done by a window sizing override

PicView/PicView/Views/Windows/MainWindow.xaml.cs

Line 126 in 9970e8c

protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo)

and a function to scale the image

PicView/PicView/UILogic/Sizing/ScaleImage.cs

Line 149 in 9970e8c

internal static void FitImage(double width, double height)

The setting "keep window centered" does not do anything, I suppose this is why?

[mardulas]

Actually it does something, it forces the window a bit up and left (from the center) when it's on. So on means it's not centered and off means it's centered. Ahem...

At least when I turn off resize window and keep centered, then it keeps the window position. Which is ok.

My apologies. The wallpaper function has been fixed in the latest version. I know it's a bit slow when effects are applied, I might improve it in the future.
