[2/3] renderer changes to support "sandwich mode" highlighting (#1418) 
This diff modifies our canvas/rendering code to support shapes rendering
into a "background layer". The background layer isn't a layer in the
sense of our own html/svg/indicator layers, but is instead part of the
HTML canvas layer and is created by allocating z-indexes to shapes below
all others.

For most shapes, the background starts at the canvas. If a shape is in a
frame, then the frame is treated as the background.

Exports now use the `renderingShapes` algorithm which fixed a small bug
with exports where opacity wouldn't get correctly propagated down
through child shapes.

2. sandwich rendering for highlighter shapes #1418  **>you are here<**
