Saves lots of time when rendering using background worker in the browser.
An even more aggressive change would be to allow
ImageBitmapas part of the interface, not onlyBlob, and then use<canvas>in the browser for rendering. That would eliminate one buffer clone (~ 40 ms in my experiments) and bring down total time to show a tile to a couple of ms only.
