Disappearing PNG on slow graphs #156

Client side png that the client has already received will cease to display when scrolling up and down when the client is still waiting on another png to come in on the server.

Reproduction: Chunk 1 is loaded, and displaying Chunk 2 is requested, but not responded Scroll down so that the start position for Chunk 1 is off the top of the screen Result: chunk 1 disappears and will not reappear without scrolling up or getting a final response for Chunk 2.
