Subtitle offset from bottom in not available for android TV ver 0.18.x

[vishnujp12]

This was a very useful feature for videos shot in Cinemascope aspect ratio, as it allowed me to easily display subtitles on the black bar at the bottom. However, with the latest Android client update, this option is no longer available, and the subtitles are now stuck in one place by default. Please consider adding this feature back if possible.
