Flicker during this._image.src switch ...

[scooterw]

There is a noticeable flicker during the switching of this._image.src. This transition period is made much longer when render / return times from the remote server are longer. To "fix" this, we move the repositioning of the image to the image onload event. This creates a VERY brief flicker, where you see the old image for a moment.

To eliminate this flicker, we could introduce a new image element that is populated and swapped programmatically. I'm not entirely certain that this is a good idea, but I am going to try this and see how it works out.

(L.AGS.Layer.Dynamic) ... On pan, the image swap seems to work nicely. On zoom change, however, the default zoom behavior causes the image to shift before it is redrawn. This may be overridden, though I'm not sure if it is worth it.
