efbffedd68 Clean up usage of SkSurfaceProps
This CL continues cleaning up Skia's usage of SkSurfaceProps. It:

  Removes the duplicate SkSurfaceProps object from SkImageFilter::Proxy.

  Removes a dispreferred ctor from SkCanvas

  Removes the initForRootLayer entry point from SkDevice (since the root device and the canvas should always have the same pixel geometry now).

9a53fd7c41 Begin kLegacyFontHost_InitType cleanup
This CL starts the process of pushing kLegacyFontHost_InitType-type SkSurfaceProps up the call stack and out of Skia. It:

 Gets rid of the default SkBaseDevice ctor. This means everyone has to always hand an explicit SkSurfaceProps to it.

 It makes public the SkBitmapDevice creation methods that require SkSurfaceProps.

 Removes (in Skia's code base) all SkBitmapDevice ctor calls w/o SkSurfaceProps.

 Makes the "recording" canvases (e.g., pdf, svg, xps) explicitly not use kLegacyFontHost_InitType.

 Replicates the creating canvas/device's flags on saveLayer devices

d8b5771779 Don't fail SkMergeImageFilter if one of the inputs are empty
If one of the inputs to a SkMergeImageFilter was clipped away or
otherwise caused the filterImage(...) invocation for it to return
false, the entire effect would be "failed" and return false --
regardless of if it had produced a result or not.
Instead of returning false directly if filterImage(...) for a source
returned false, consider all the inputs, and then only return false if
all of them do.

24e06d5244 Remove uniqueID from all filter serialization.
(This is essentially a revert of https://codereview.chromium.org/503833002/.)

This was necessary back when SkPaint was flattened even for in-process use. Now that we only flatten SkPaint for cross-process use, there's no need to serialize UniqueIDs.

Note: SkDropShadowImageFilter is being constructed with a croprect and UniqueID (of 0) in Blink. I've made the uniqueID param default to 0 temporarily, until this rolls in and Blink can be changed. (Blink can't be changed first, since unlike the other filters, there's no constructor that takes a cropRect but not a uniqueID.)

a9d9a39238 Read pixels in BGRA non-premul mode in few tests
The tests assert on Sk_ColorGREEN, which is in BRGA non-premul. Read the
pixels in same color format.

Currently the tests pass on all platforms because GREEN is fully opaque
and the component stays in the same place both on BGRA and
RGBA. However, hypothetically somebody could copy-paste the assertion
for further tests but use, say, RED. This creates latent error that is
only visible on some platforms like mac.

32673b99a4 Allow negative values in SkBlurImageFilter sigma.
There are two ways negative sigma values may occur: in
the original filter parameters, or after multiplication
by a negative scaling CTM. The former case is
invalid according to the spec, so we continue to check
for it at validation time. In the latter case, we should
interpret it as a horizontal flip in the kernel pixel
access, and simply take the absolute value (since the
filter kernel is symmetric).

Also refactor all this logic into a single place for the
CPU, GPU and onFilterBounds() paths.

1150a6d151 Fix recursive computation of filter bounds for drop shadow,
morphology, blur.

[Reland with fixed tests.]

Because we're computing "backwards" from a clip rect of destination
pixels to be filled to the required source pixels, we should use tail
recursion rather than head recursion in onFilterBounds().

This actually only makes a difference for drop-shadow, where
the computation is non-commutative. Blur and morphology commute, but I
moved them to tail recursion anyway for clarity (so all onFilterBounds
use tail recursion).

d910f54443 Fix saveLayer() with a pixel-moving filter vs SkBBoxHierarchyRecord / SkRecordDraw
In SkBBoxHierarchyRecord:
  Since the bounds we pass to saveLayer are in the pre-filtering
  coordinate space, they aren't correct for determining the actual
  device pixels touched by the saveLayer in this case.

  The easiest fix for now is to pass the clip bounds, since the final
  draw done in restore() will never draw outside the clip.

In SkRecordDraw:
  We do adjust the bounds passed to saveLayer, so we just need to make
  sure that when we're using a paint that may affect transparent black,
  we ignore the calculated bounds of draw ops and use the clip intersected
  with those adjusted bounds.

9fa60daad4 Simplify flattening to just write enough to call the factory/public-constructor for the class. We want to *not* rely on private constructors, and not rely on calling through the inheritance hierarchy for either flattening or unflattening(CreateProc).
Refactoring pattern:

1. guard the existing constructor(readbuffer) with the legacy build-flag
2. If you are a instancable subclass, implement CreateProc(readbuffer) to create a new instances from the buffer params (or return NULL).

If you're a shader subclass
1. You must read/write the local matrix if your class accepts that in its factory/constructor, else ignore it.

55b6d8be99 Implement a persistent uniqueID-based cache for SkImageFilter.
Add a unique ID to SkImageFilter, and use it as part
of a persistent cache of image-filtered results. This is used for
caching frame-to-frame coherent filters.

We also keep track of which filter subtrees do not reference the
src input, and use a GenID of zero for the src input in that case.
That way, subtrees which are not dependent on the filter input can be
cached independently of it.

This gives approximately a 4X speedup on
letmespellitoutforyou.com/samples/svg/filter_terrain.svg on Z620
and Nexus10. The cache key consists of the uniqueID of the filter, the
clip bounds, the CTM and the genID of the input bitmap.

Since this does not yet handle the case where the input primitives
(and part of the resulting filter tree) are unchanged, we have
to keep around the external cache for that painting case.
When the work to cache unchanging input primitives is done, the
old cache can be removed, and the new UniqueIDCache will be renamed
to Cache.

837f5321a4 Fix for saveLayer() with filters vs. the BBox Hierarchy.
When building acceleration structures for SkPicture, we must transform
the primitive's bounds not only by its own SkPaint, but by the paints of
any saveLayer()s currently active above it.

We do this by pushing the SkPaint onto a stack on
saveLayer(), and popping them on restore(). We also push
a NULL paint in save(), so that the pushes and pops are
balanced.

c07e2811dd Revert "Fix for saveLayer() with filters vs. the BBox Hierarchy." and
"resizeimagefiler is ok with a BBH now".

This reverts commits 6ca0b6a46c and 8fa73202ea.

Apparently causing problems in SKP playback.

9ea3d57fde Clean up SkImageFilter constructors.
Now that all creation of SkImageFilters goes through
factory Create() methods, there's no real reason for the
convenience constructors. Some SkImageFilter subclasses
which actually have zero DAG-able inputs were passing NULL
to the superclass constructor. This actually means 1 input,
with a NULL value, not zero inputs. This becomes more
relevant for the upcoming cache infrastructure, where this
indicates that the filter will use its src input, where in
fact some of these filters do not (they are image generators
only).

Limiting SkImageFilter to a single constructor resolves this
ambiguity.

Along the way, I removed all of the default parameters to
the constructors, since the Create methods always call them
with the full argument list.
