Culling API
*** SKP format breaking change ***
Adding a couple of culling primitives: pushCull(SkRect) & popCull().
These are currently only plumbed for SKP playback quickreject.
At record time, we perform a couple of optimizations to trim down the
number of redundant culls:
* collapse empty pushCull/popCull pairs
* skip pushCull/popCull pairs nested within an identical cull rect
Things still missing/to consider:
* use an inlineable, simplified quickreject (Mike's old prototype)
* debugger visualization for cull boxes
* BBH integration: the initial prototype had some minimal BBH support,
but since the optimizations required expensive rewinds and culling
is expected to be a BBH alternative, it got dropped.
