* Draws originate from a different thread so the surface could change
* at any moment while we try to draw until we lock the canvas.
*
* Also, never try to lock the canvas while holding the surface lock
* unless you're in SurfaceChanged, in which case the canvas was already
* locked. Surface lock -> Canvas lock will lead to AB-BA deadlocks.
