This Vaadin sponsored GWT library contains a basic support for Pointer Events. The library supports both prefixed version in IE10 and non-prefixed version in IE11+.
At least GWT version 2.6.0-rc2 is needed to use this library.
The implementation is pretty much the same that will most likely appear built into next major Vaadin version, but can be thrown into any GWT project.
Module name to inherit is "com.vaadin.pointerevents.PointerEvents"
Builds will be available via https://vaadin.com/directory
