b4511344b6 Minor refactor of GrLayerHoister
The main point of this CL is to make sure using the rect bounds (rather than the underlying texture's bounds) is acceptable in GrLayerHoister::FilterLayer.

This is split out of https://codereview.chromium.org/1943913002/ (Retract GrRenderTarget from GrLayerHoister)

9db912c2ac Sketch splitting SkPicture into an interface and SkBigPicture.
Adds small pictures for drawRect(), drawTextBlob(), and drawPath().
These cover about 89% of draw calls from Blink SKPs,
and about 25% of draw calls from our GMs.

SkPicture handles:
  - serialization and deserialization
  - unique IDs

Everything else is left to the subclasses:
  - playback(), cullRect()
  - hasBitmap(), hasText(), suitableForGPU(), etc.
  - LayerInfo / AccelData if applicable.

The time to record a 1-op picture improves a good chunk
(2 mallocs to 1), and the time to record a 0-op picture
greatly improves (2 mallocs to none):

    picture_overhead_draw:   450ns -> 350ns
    picture_overhead_nodraw: 300ns -> 90ns

478dd72336 Fix layer hoisting image filter corner cases
This CL fixes 5 bugs related to hoisting image filters:

For image filters the src layer (the one prior to filtering) often needs to be
smaller then the final layer. This requires the saveLayer's optional bounds
to be stored (in SkLayerInfo.h and SkRecordDraw.cpp) and then used in
compute_source_rect and carried around in GrCachedLayer.

The image filters can add an extra offset to the final draw operation.
This is now computed in GrLayerHoister::FilterLayer and  carried around in
GrCachedLayer.

Filtered layers must use exact matches. This is now done in GrLayerCache::lock.

The filter cache requires a valid matrix so it can compute the correct offset.
This is now done in GrLayerHoister::FilterLayer.

Filtered layers need to be drawn with drawSprite while unfiltered (and therefore
hopefully atlased) layers can be drawn with drawBitmap. This is now done in
draw_replacement_bitmap.

01d6e5f462 Use variable length key (rather than accumulated matrix) as save layer hoisting key
Adding the rendering canvas' CTM to the layer hoisting key (i.e., Add support for hoisting layers in pictures drawn with a matrix - https://codereview.chromium.org/748853002/) has increased the cache miss rate due to accumulated floating point error. This CL fixes part of the issue by using the chain of operation indices leading to each saveLayer as the key. The canvas' CTM must still form part of the key but should be less subject to accumulated error.

3aac6e0848 Add clip to layer cache
This CL adds the clip region to the GPU layer hoisting image cache. It also switches back to the old caching behavior of using the entire CTM in the cache key rather then just the upper 2x2. This latter change is to focus more on hoisting rather then caching.

It also includes 2 smaller fixes:
a) layer's that have an image filter are no longer atlased (b.c. doing so complicates applying the image filter)

b) the result of clipping the layer's bounds to the current clip is used as the hoisted layer's size. This reduces the amount of pixels drawn to match a normal (non-hoisted) draw pass.

7bb9ed756e Fix bug in GrCachedLayer reuse
In the new MultiPictureDraw tests a single hoisted layer is reused multiple times. The previous plot locking scheme allowed GrCachedLayer objects to be aggressively deleted prematurely leaving the reusing GrHoistedLayer objects with dangling pointers.

This CL changes adds a new pseudo-ref to GrCachedLayer. (It can't be a real ref since the cached layers aren't deleted when it goes to 0).

ed42059d2f Move offset and CTM from LayerCache Key to per-hoisted-layer info
This CL reduces the amount of information used in the layer cache key:
- the stop value isn't needed since the start value uniquely identifies the layer in the picture.
- only the upper-left 2x2 portion of the CTM should be used as a key for looking up cached layers.
- individual layers can be redraw in different locations so the final offset cannot be a part of the key.

Since this data is no longer stored in the cached layer, but is still required to draw the cached layer, it is now stored in the per-layer information (i.e., HoistedLayer).

This is split out of (Fix sub-picture layer rendering bugs - https://codereview.chromium.org/597293002/).

6f294af43b Refactor GrLayerCache for new API
The only substantive change in this CL is skipping atlasing
for any layers that are involved in nesting. Prior versions
have allowed nesting layers to be atlased.

--------------------------------------------------------

All times are on Windows with a repeat count of 200.
Format is: <time in ms> (<# of glBindframebuffer calls>)

How to interpret this:

For the boogie page:

 both columns should be the same (since boogie has no
        nested layers)
 without the new API the tiled case doesn't show any real
        benefit from hoisting

For the carsvg page:

 The nesting change does increase the number of FBO
      switches but doesn't kill performance
 Because of the location & size of the layers the
      tile case does show some improvement (even
      without the new API)

0c42332859 Add CTM to the cached layers' key and reduce render target pingponging in layer pre-rendering
The CTM is required on the key so we will re-render when necessary.
The SkGpuDevice change ensures big layers in the midst of atlas-able layers don't cause a render target switch.

320c92380f Add plot-based purging to GrLayerCache
This CL allows a GrPlot full of atlased layer to be purged from the atlas to make room for new layers.

d771f6bc27 Add auto purging for SkPicture-related Ganesh resources (esp. layers)
This is intended to lower the bookkeeping burden for the Layer Caching feature. Cached layers are now automatically purged when a picture is deleted.

e904c09a3a Fix alpha textures in NV ES3 contexts on Windows.
Make unit tests iterate over all the rendering GL context types rather than using kNative.

Fix the extension printing when gStartupSpew is set.

21048b588f Always have GrLayer's rect be valid
This CL just makes atlasing easier/clearer since there is a separate atlased query method. Not using the rect as a signal also simplifies the rendering of the layer in SkGpuDevice.cpp.

This is calved off from (Add atlased layer purging - https://codereview.chromium.org/367073002/)

This cannot be landed until (Chrome: Switch to one-at-a-time SkPicture::clone interface - https://codereview.chromium.org/380323002/) has landed.

952841bf41 Begin atlasing
This CL makes it possible for pulled-forward-layers to be atlased. It currently has a couple glaring limitations (which is why it is disabled):

1) the atlased layers cannot be purged nor aged out
2) the texture backing the atlas is not pulled from (or returned to) the resource cache

#1 is on hold until we have a recycling rectanizer

A separate major limitation (the non-atlased layers aren't cached) is blocked until we can transmute entries in the resource cache from scratch to non-scratch while potentially preserving their contents.
