            Bug ID: 744763
           Summary: gltransformation: Make all property into universal
                    [0-1] coordinate
    Classification: Platform
           Product: GStreamer
           Version: git master

          Priority: Normal

     GNOME version: ---

Currently the translation properties range to is base on the video proportion.
It's a bit a work for the application to figure this out and do that math,
specially that aspect ratio may change if the video change.

What I'm proposing instead, is to change the properties, so they are expected
in universal coordinate, like in GL. Where a translation of +1 would make the
image go out of view.
