To facilitate demo code consolidation, introduce a custom property manager which filters for node names starting with '$' and treats all properties sharing the same name unitarily. Update the Colorize GM to use this new helper. Also revisit the PropertyObserver interface: * aliases for client-facing value types * introduce a new (decomposed) TransformPropertyValue, to replace component-wise setters * consolidate the PropertyHandle interface to only expose get()/set() Bug: skia: Change-Id: I9aa9ee80c1fb57bbfbacab0fc3f017da909b24d9 Reviewed-on: https://skia-review.googlesource.com/c/173220 Reviewed-by: Mike Reed <reed@google.com> Commit-Queue: Florin Malita <fmalita@chromium.org>
