5a3bcc716b Not using requestAnimationFrame 
Using the Timeline tab of the Chrome Developer Tools, no significant
difference of Paint events can be observed when requestAnimationFrame is
used. So I agree with @elemoine that there is no need to introduce
asynchronous behavior here.

ff4a1b2468 Optimizing positions for rendering 
Calculating pixel positions from origin and grid index causes alignment
issues in the grid. By going back to incremental positioning, we get a
result without blank spaces between tiles again.

7e5e221c8d Image loading performance improvements 
Performance improvements are achieved by using requestAnimationFrame when
a tile's visibility changes, and by not starting with a blank image when
creating a new tile image. It seems that even Firefox does not show a
loading placeholder when the tile is made visible in an animation.

ff1f99a03f Don't reuse tile images unless we have a new url to load. 
Without this change, some browsers don't cache the images. See #454 for a discussion about this issue.

a05eab29db Adding tileloadstart event to layer. 
For this to be useful (i.e. so listeners can see/modify the tile url), a change in Tile.Image is required so we do not fire the loadstart event before we have the url to load.

dde45696f7 Simplified tile queue; using the tile's beforedraw listener. 
Since draw is the only tile operation that we defer, the tile queue can be an array of tiles and queue handling can be simplified. We now use the beforedraw event to defer drawing, and remove all occurrences of a tile from the tile queue when we draw it.

Instead of layers that want to defer tile drawing having to override the tile's draw method, layers can now abort drawing by returning false from a beforedraw listener, and later call draw(true) to draw the tile directly, without clearing it first.

fe202cef14 Change getUrlAsync parameters. 
Instead of giving the function a bound, a scope, a property to update
and a callback, only give the bound and a callback.

When the url is retrieved by getUrlAsync, simply call the callback
with the url as argument and let the caller manage this.
