Sub Tasks

Description
The BufferedContext.invalidateContext() only resets the state of the 
BufferedContext, but not the native one. This may lead to 
de-synchronization between these.

For example, if a transform is set, and then context is invalidated,
the native device may have the transform set.

EVALUATION

We need to reset the native state (transform, clip, etc).

This bug was uncovered by the fix for 6664068 where we
sometimes invalidate the context.
