[Cogl] Out of graphics memory resizing or packing atlas

[Roy Amodeo]

Hi Robert,

I just wanted to thank you again for your quick response.

I also thought I'd share the workaround that we used to move forward. At
best it's only part of the solution, but it was enough for us to recover
somewhat gracefully.

The patch was generated from commit
13861b710fc2e78e9f3c6042967817d5da7df9a0 (tag: 1.10.4).
