16dbdc64changed the padding around the app icon in the titlebar to be applied both vertically and horizontally rather than only horizontally because it was more natural from a developer's perspective, but some users complained about the smaller icons in certain configurations. So let's undo the change in16dbdc64and apply the icon padding only horizontally for now. We can add configurations for the icon padding (or icon size independent from window.button.{width,height}?) later.
