Created an attachment (id=157444)
 --> (https://bugs.webkit.org/attachment.cgi?id=157444&action=review)
debug code

With this patch I see that:
Atlas cache fail; requiredDim=512, bufsize=4000000, usedBytes=1572864
a lot of times. So if I'm not wrong we use only ~1.5 MB from the ~4 MB surface we allocate (maybe a bit more for smaller tiles but those are rare so it does not make it much better).
