* This class serves as a proxy between Skia's SkCanvas and Android Framework's
|
|
* Canvas. The class does not maintain any draw-related state and will pass
|
|
* 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.
