4ab5a9048c Discard atlas after every MultiPictureDraw::draw
This is intended to prevent ghosting on tiled architectures.

This CL also defers creation of the atlas (and its texture) until it is actually needed.

fd61ed0d79 Alter layer hoisting to only hoist layers for one canvas at a time
This CL alters layer hoisting to defer creation of the free floating layers until they are actually needed (rather than creating _all_ the hoisted layers at the start).

It also fixes a pre vs. post Concat bug with how matrices were being accumulated.

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/).

4aa6dfc0b7 Separate replacement creation from layer discovery
This is a simple refactoring that sets the stage for eliminating GrReplacements::ReplacementInfo and splitting up EXPERIMENTAL_drawPicture to support multi picture draw.

4815fe5a0a Fix bug in layer hoisting transition to SkRecord backend
Care must be taken when setting up the initial CTM matrix for partial SkRecord playbacks b.c. all the setMatrix calls will concatenate with the initial matrix (which may be different then the CTM that is required to draw correctly).

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.

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/)

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.
