[vlc-devel] [PATCH v2 07/29] opengl: simplify opengl_init_program() call

[Romain Vimont]

Do not pass extensions to opengl_init_program().

This was an optimization not to retrieve the extensions list twice.
However, since the initialization will be moved into a separate
component (the renderer), we don't want to expose this internal detail.
