Replying to [comment:9 ahocevar]:
This is impressive work! Thanks Andreas.
> * The lag when dragging layers on mobile devices was caused by a reflow
after a tile image was loaded. This reflow is not needed any more, so the
tileLoadingDelay on the Grid layer has now a default of 0ms instead of
100ms.
Would you mind elaborating a bit? Why there was a reflow after a tile
image was loaded? And why there's no reflow anymore?
My preliminary tests show that delaying tile loading still improves the
panning experience.

these browsers as well. Thanks for any review. If there is interest and it
makes reviewing easier, I can set up a sandbox with this patch.
