tests: simple-decoder: set window size to the surface dimensions.

Browse source 
Set the window size to the decoded surface dimensions, if the user has
not requested the application to run in full-screen mode. Besides, no
effort is made to preserve aspect ratio or to center the video within
the mapped window.
