Comment(by rangoy):

 Great work with this patch.

 I am trying to use this (I currently test from the OpenLayers 3 git-repo),
 and I am experiencing an a bit annoying artifact: In some browsers there
 is a white bar between the tiles.

 I've tried two approaches to fix this;
 * I've tried to use translate: transform/scale on the div. The white bars
 dissappeared, but other elements ended up in the wrong place. (This is
 probably because i don't quite grasp how the positioning is done).
 * Setting the the tilesize=divsize (100px) seems to solve the issue also.

 As I far as I can see, there are two things which might improve the issue;
 * Change the divsize to match the tilsize -  it seems like the problem is
 an rounding error somewhere.
 * Implement it by using translate; transform (or even transform3d). I
 suspect that this approach needs to be implemented with an fallback as not
 all browsers support this.
