These are bugs uncovered by the integration test for embedded Android
views:
* Some PointerEvents were constructed with radiusMinor set to
radiusMajor.
* Some PointerEvents were missing radiusMajor/radiusMinor.
* The pressure parameter was not passed to PointerUpEvent.
* radiusMin, radiusMax, radiusMinor, and radiusMajor were not
converted from physical pixels to logical.
Sending the fixes without a test as the bugs are covered by the integration
test that is going to land soon.
