This should be a strict refactor, just pulling out the bounds array.
(It's the rescued nice parts of a dead-end CL targeting skia:4492.)

When computed, the RTree for an SkPicture will have a root
bounds that reflects the best bounding information available,
rather than the best estimate at the time the picture recorder
is created. Given that creators frequently don't know ahead of
time what will be drawn, the RTree bound is often tighter.
Perf testing on Chrome indicates a small raster performance
advantage. For upcoming painting changes in Chrome the
performance advantage is much larger.

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases. We'll have to manually clean up the rest
over time unless I level up in regexes.
for f in (find . -type f); perl -p -i -e 's/virtual (.*)SK_OVERRIDE/\1SK_OVERRIDE/g' $f; end

Idea:
1. in its mutable recording state, keep a table of drawables on the side, and store an index in the record list.
2. In "immediate-mode" draw, just call the clients drawable directly (need access to our private list to turn the stored index into a proc)
3. when we "snap", we replace the list of drawables with a list of (sub) pictures, and then during playback of the snapped picture, we invoke a private drawable which just calls "drawPicture" on the index'd subpicture.

This CL shrinks the bound computed for saveLayers that possess both an explicit
bound and a complex paint (e.g., one that affects transparent black). In this
case the bound of the layer should be the clipped explicit bound rather then
the clip prior/after the saveLayer/restore block.
In the following the first bound is the currently computed bound
while the second is the new/desired one:
For a 100x100 picture
saveLayer (no bound, no paint) [ 0 0 100 100 ] [ 50 50 100 100 ]
setMatrix (translate 50, 50) [ 0 0 100 100 ] [ 50 50 100 100 ]
saveLayer (bound of 0, 0, 50, 50 - complex paint) [ 0 0 100 100 ] [ 50 50 100 100 ]
restore [ 0 0 100 100 ] [ 50 50 100 100 ]
restore [ 0 0 100 100 ] [ 50 50 100 100 ]

This should produce tighter conservative bounding boxes for text than the
approximation code it replaces.
Recording performance is neutral on my desktop. Playback performance
improves by up to 15% on text heavy pages, e.g.
desk_pokemonwiki.skp_1 3.24ms -> 2.83ms 0.87x
desk_baidu.skp_1 1.91ms -> 1.58ms 0.83x

- The expected case is now a single bulk-load insert() call instead of N;
- reserve() and flushDeferredInserts() can fold into insert() now;
- SkBBH subclasses may take ownership of the bounds
This appears to be a performance no-op on both my Mac and N5. I guess
even the simplest indirect branch predictor ("same as last time") can predict
the repeated virtual calls to SkBBH::insert() perfectly.

This is basically how blink uses the filter. Currently, I can't use it for "ShadowOnly" mode with the filter at all, but instead of copying the code and risking to have the codepaths diverge, I'm simply going to add the option here.

I want to play around with how SkTileGrid stores its tiles. Having a
cap on the number of insert() calls can be pretty handy.
While I'm at it, I gave flush() a default empty impl. Like reserve(),
it's really an optional hook for subclasses.

Now that the old backend's not using BBHs, we can specialize them for
SkRecord's needs. The only thing we really want to store is op index, which
should always be small enough to fit into an unsigned (unsigned also helps keep
it straight from other ints floating around).
This means we'll need half (32-bit) or a quarter (64-bit) the bytes in SkTileGrid,
because we don't have to store an extra int for ordering.

It makes no sense for the paint from a saveLayer to effect anything outside its saveLayer/restore block. But as currently written, we'll adjust the clip bounds just after a restore by that paint.
Turns out the test I wrote for the last CL (which caused this bug) actually had the bug baked into its expectations. I've updated them and added some notes to explain.
