Use state machine to track tile state
bug:5369978
Manage invalidations, painting, transferring, and swapping with a
state machine.
notes:
* readyFor shouldn't be needed if all of the events that would cause a readyfor
fail mark the tile dirty (such as stealing, scale change)
* changing the scale of a page should discard all textures
* m_dirty should be more gracefully worked into the state machine
* a tile may drop dirtiness notifications if it's already painting, since upon
completion m_dirty will be cleared - (issues for layers only)
