Notes: | |||
* Just implementing Touch Events and touch-action (without Pointer Events) would allow efficient Pointer Events polyfills, and other developer benefits (including ability to improve responsiveness of touch UIs). This is what Chrome is currently doing. | |||
* Implementing APZC on desktop would allow desktop Firefox to share much of the Touch Events / Pointer Events / touch-action code with Firefox OS. | |||
** Similarly, porting Firefox for Android to the Gecko APZC and meta viewport code would allow increased code sharing with Firefox OS. | |||
