Fix: Soft keyboard issue in Android

[pobch]

Why?

We already fixed soft keyboard issue in iOS:

• Fix: soft keyboard messes up the canvas size #35

By the way, things are difference in Android:

Android: document.documentElement got resized when the soft keyboard appears
iOS: document.documentElement maintains the size even though the soft keyboard appears

How?

• Remove resize event listener. No more auto-resize the canvas while the screen size is changing.
• Set the canvas width/height only once at the first render
• In case the screen size changes, a user needs to manually click a button to recalculate the canvas width/height
