<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/243644">r243644</a> - [GStreamer] imxvpudecoder detection and handling
https://bugs.webkit.org/show_bug.cgi?id=196346
Reviewed by Xabier Rodriguez-Calvar.
When the imxvpudecoder is used, the texture sampling of the
directviv-uploaded texture returns an RGB value, so there's no need
to convert it. This patch also includes a refactoring of the
ImageRotation flag handling. The flag is now computed once only
and stored in an instance variable.
