[Cogl] [PATCH] cogl-gst: allocate textures synchronously

[Robert Bragg]

From: Robert Bragg <robert at linux.intel.com>

This makes sure video textures being uploaded via
video_texture_new_from_data are allocated before the function returns.
This function create a CoglBitmap to wrap the data from gstreamer and by
allowing cogl to allocate the texture lazily it's possible that the data
being pointed to by the bitmap won't remain valid until we actually come
to allocate the texture.
