* through most requests directly to the Canvas provided in the constructor.
*
* Upon construction it is expected that the provided Canvas has already been
* prepared for recording and will continue to be in the recording state while
* this proxy class is being used.
*
* If filterHwuiCalls is true, the proxy silently ignores away draw calls that
* aren't supported by HWUI.
