Detailed Description

Mark a scope whose GL objects have lost the context that owns them.

Deleting a GL object requires its own context to be current. A canvas whose native window is already gone cannot make its context current, and every 3D canvas owns an unshared context, so a delete issued then would be executed against whichever context is current and would destroy an unrelated object carrying the same name. Names are released when the owning context is destroyed, so skipping the deletes leaks nothing.

Only the thread holding the context issues GL commands, so no locking is needed here.
