Changing scaleX or scaleY on a MatterImage or MatterSprite would cause the body scale to become distorted as the setters didn't use the correct factor when resetting the initial scale. Fix #4206

@ -230,6 +230,7 @@ one set of bindings ever created, which makes things a lot cleaner.
* `Utils.Array.MoveUp` wouldn't let you move an array element to the top-most index in the array. This also impacted `Container.moveUp`.
* The Texture Tint Pipeline had a logic error that would cause every 2001st quad to either be invisible, or pick-up the texture of the 2000th quad by mistake. The `batchQuad` and `batchTri` methods how handle re-assigning the batch texture if they cause a batch flush as part of their process.
* Rotating Sprites that used a Normal Map wouldn't rotate the normal map with it, causing the lighting effects to become irregular. The normal map vectors are now rotated correctly (thanks @sercant for the PR and @fazzamatazz and @ysraelJMM for the report)
* Changing `scaleX` or `scaleY` on a `MatterImage` or `MatterSprite` would cause the body scale to become distorted as the setters didn't use the correct factor when resetting the initial scale. Fix #4206 (thanks @YannCaron)
