change scale comparison from 0.95 to 0.9999 to stop 'snapping' of poster and video during resize

When resizing a player there is a noticeable 'jump'/'snap' of poster images/video content.

See example video: http://embed.reelfeed.tv/jwplayersnapping/

By changing the size comparison in these 'Stretching' utilities, the snapping is all but gone.
