From 6353b3d2f43f5899ebecab13b82ecadacdbb69b3 Mon Sep 17 00:00:00 2001 From: Saivan Date: Tue, 26 Jun 2018 22:42:47 +1000 Subject: [PATCH] Allowed the origin to stay fixed as we animate transforms This commit start to remove the expensive bbox calculation by assuming that the origin stays at a fixed point during an animation. This is a good assumption as transforms don't change the bbox of the element.
