Merge lp:~andreas-pokorny/mir/fix-surface-information-not-propagated-to-android-input-stack into lp:mir

[Andreas Pokorny]

Updates the InputWindowInfo found at InputWindowHandles everytime the InputDispatcher tries to querry the object for hit testing.

 So far that information was only updated during creation (because we triggered that in the mir implemantation) and when focus changes occur - that might be the reason why unity8 never experienced these issues. This fix kind of makes updateInfo and the interface of InputWindowInfo even more questionable. Why have those members public? Why update these only under certain circumstances..

This changes updates the InputWindowInfo that is provided to the android InputDispatcher for each surface and application (?) just before those objects are tested against touch positions.

+1. Your suspicion is right that WindowInfo and GetInfo is ugly. We inherited it from android input. I think in particular they used it to solve threading issues with the C++ input stack and a WindowInfo implementation on the Java side.

Verified bug 1268819 is fixed! However bug 1261647 is not (try the test case in the bug description). Unlinking the second bug for now...

ah ok, fingerpaint being fullscreen on start is a bad test subject. Will dig again.
