Pass expose event to backend enter and leave functions

This is needed for clipping.  Unfortunately, the puglEnterContext() and
puglLeaveContext() API was not suitable for this, but this shouldn't matter in
user code because it is only used for setup, and is slated for removal anyway.

Instead, just call the backend functions directly in the implementation.
