[ON TRACK] A11y + Windows 8 Touchscreen Support

A11y and touchscreen support has landed in 51. We are still targeting 52 for release.

We are working to obtain confirmation that current state/planned state for Release represents a usable, shippable level of support.

We are basically in convergence and are tracking the issues we would like to fix before rolling out, here.

Touch events for APZ has landed in 52.

NVDA is the first client we plan on achieving compliance with. We feel that if A11y can work with NVDA, we should be at about 90% of functionality with other, similar clients.
