[PATCH weston v2 1/2] gl-renderer: Take a list of acceptable formats in create functions

Fri May 15 10:12:39 PDT 2015
Currently we pass either a single format or no formats to the gl renderer
create and output_create functions. We extend this to any number of
formats so we can allow fallback formats if we don't get our first pick.
