st/texture-cache: Ensure icons keep their aspect ratio when scaled down

Browse Source 
Window preview icons can get scaled down if the window they belong to is
very small and/or there are a lot of open windows. When scaled down this
way the icons would get scaled without keeping the aspect ratio. Fix
this by using a content gravity that keeps the aspect ratio.
