Sometimes the only motion event that is above the keyboard is the UP
event. In that case we can't expect one more event to come that will
dismiss the extension. So don't show the extension if the only Y < 0
event is an UP event.

Don't try to show the extension if the main keyboard is not showing.

This was due to the multi-touch error correction code that was recently
added. Make sure that one of the move points is in the upper 3 rows
to allow for fast swipe on spacebar.

Detect sudden moves that have a large delta that would not be a typical drag
by the user when hunting for a key. Drop move events until the user releases
the touch and register both starting and ending keys instead of only the
ending key. This reduces the frequency of dropped keys on touch hardware that
isn't able to detect multi-touch reliably.

This also takes into account diagonal moves or right angled moves due to
pseudo-multi-touch.

It weakens the swipe gestures (to swipe, you'll need to swipe slowly and fully,
  otherwise it will trigger 2 keys)

This might also fix the keyboard closing suddenly when using the extension.
Re-enable bubble for landscape extension keyboard, since the framework can
now display it to the side.

Also add a summary text in the input language list for languages with
a dictionary so that users don't feel cheated when they pick a language
that doesn't happen to have a dictionary. Remove greek as it isn't an
extension of the QWERTY keyboard.

Move java code to a different directory so that the unbundled
version doesn't try to compile the native code again.

This increases the chance of hitting the correct letter when typing a word
that exists in the dictionary, rather than only correct it after the fact.
It is most effective after 2 or 3 letters of a word have been typed and gets
more accurate with more typed letters in the word.

If 2 adjacent letters have similar probabilities of occuring, then there is no
hit correction applied.

Shows the language on the spacebar and in the preview bubble. Allows
dragging of the spacebar from side to side to switch to previous or
next languages.

This is a temporary solution until slide-on-space is implemented.

the change to logging to remove any private dependencies and use
broadcast intents to VoiceSearch instead.

I have audited this code and it appears good to go for open-source,
but would appreciate a second pair of eyes.

Still to do after submitting this CL:

* Reintroduce Amith's memory leak fix (37557) which was the only CL
  added to LatinIME since the last merge over to the private copy.
* Make some changes to allow LatinIME to work without voice search
  installed. Currently I believe it will show the mic but fail if
  you press it. We need to base the visibility on the mic on the
  availability of the service.
* Fix this code to use the new Gservices framework, it's still trying
  to use the old one.

New feature to enable fast switching between input languages for
multilingual users. Keyboard settings lets you select a bunch of
languages to switch between from the Latin IME.

Use the Globe icon to toggle between languages.

Needs more work and some layout changes in specialized keyboards.

Also added a Russian keyboard (needs some pixel TLC at the right edge).

Slide up on keyboard to get an extended keyboard for numbers and
punctuations. This is work in progress...

Use new API in KeyboardView to invalidate all keys on long-press of shift key.
