Merge "Round animation progress for computing size for background" into oc-dr1-dev am: 75176be7

        // Compute new scaled width and height for background that will depend on current animation

        // progress. Those consist of current crop rect for the main surface + scaled areas outside

        // of letterboxed area.

        // TODO: Because the progress is computed with low precision we're getting smaller values

        // for background width/height then screen size at the end of the animation. Will round when

        // the value is smaller then some empiric epsilon. However, this should be fixed by

        // computing correct frames for letterboxed windows in WindowState.
