* Don't reset cache while zooming using a gesture
This reuses the cached canvas while the gesture is happening. Once it has stop updating, then recompute the cache with the proper zoom.
This should massively improve performance when panning on big scenes on mobile
Fixes#1056
* update snapshot tests
* [WIP] Add names next to pointers
This implements the rendering and messaging across. Still need to do the UI to set the name.
Also, not really sure what's the best place to send the name and store it.
* Add randomized names

My original hack to put the scale when we create the canvas element doesn't make much sense. It should be done when we are rendering the scene. I moved it there in this PR.
The rest was all about forwarding the scale to where it's needed.
* Stop using getTransform
Fixes#861
The original motivation behind this is to make it work with Firefox. But it also helped make the code more intentional.
Test Plan:
- Create one square, select it, zoom in repeatedly, make sure that it zooms centered in the screen and everything looks good
- Scroll at various zoom levels, things look good
- Export a small scene at 1x and 3x, make sure the background is properly set and look good
