Kit Kat UI issue

I know that you have been looking into the display issue in Kit Kat (6033).  I offer the following in case it is useful.

This code was something I briefly worked on 7 months ago and then dropped because it didn't seem to be particularly beneficial at the time, when compared with what K-9 was already doing.

Basically, the intent was to implement the AOSP Email solution for incorporating a Webview inside a ScrollView, while still being able to scroll diagonally.  It was intended to replace the functionality of TitleBarWebView which K-9 Mail is currently using.

I just now rebased my old code on master and tried it out in an emulator with Kit Kat.  It doesn't seem to suffer from the display issue.

I don't have a device with Kit Kat, and I don't much enjoy struggling with an emulator, so I leave it to others to evaluate whether there is anything useful here.  I also don't want to unnecessarily duplicate efforts.
