Slimming Clank meeting notes 12/14

[Alexandre Elias]

Round-table sync on recent progress

Input dispatch discussion:

- Window can't mandatorily be the root of input dispatch because WebView doesn't have a window.  Therefore have a generic class called InputDispatcher for this instead

- Key and IME events are a bit different than touch events in that they go directly to the focused element without needing a hit test.  But they still need to bubble up through the view hierarchy if unhandled.

- Key events can be sent directly to WebView, bypassing IME system.  Had bugs with this in the past (doesn't affect Chrome)

Potential work for new team member Khushal:

- Separate thumbnail readback from frame drawing

- Stop using layer compositor

   - Might be tricky to incrementally move to stateless approach because that will cause performance regression as long as we're still using the layer compositor

- Centralize authority to remove thumbnails from the cache

Long discussion on public API rules, Bo will send out a doc when finalized
