Teach RenderScriptRuntime about changed context representation.
Browse files Browse the repository at this point in the history 
Summary:
The runtime discovers contexts through RenderScriptRuntime::Capture*()
methods.  These methods see the low-level context representation.
However, the runtime calls APIs that require the high-level context
representation.  Therefore, it needs to call yet another API to find
the high-level representation associated with a given low-level
representation.
