Toggle diff mask - Should toggle the diff mask in the active diff view.
Note that the extension API doesn't allow to directly get the active webview
so detection is based on visibility state changes. Therefore it might be
sketchy.
Extension Settings
image-diff.viewer.minScaleOne - Will always have 1 or less as the minimum scale
image-diff.diff.defaultAlign - Sets the default diff alignment for images with different dimensions.
Known Issues
This extension is in very early days. And it's subject to change anytime.
