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).
Increase key height in portrait.
Increase spacebar width and reduce punctuation width.
Increase vertical target area for spacebar to avoid accidentally
hitting "V" and "B".
Increase height of candidate strip.
Don't auto-correct if the typed word has more than one uppercase letter.
Also, delay applying shift state to the keyboard so that fast backspaces are not interrupted by the
time taken to render the shifted/unshifted keyboard.
