In the current implementation, SkImageFilter::Cache maintains a hash map
that maps SkImageFilter's uniqueID to an array of keys, and its purpose
is to remove the values in Cache that are associated with this array of
keys that are indexed by uniqueID. However, maintaining this hash map
causes perf regression to smoothness.tough_filters_cases.
This CL removes the id<-->key hashmap. Instead, we maintain an array of
keys in SkImageFilter. Whenever there is a new key, we push it into the
array. In ~SkImageFilter(), we call Cache::purgeByKeys to remove all the
values that are associated with the keys that are maintained by SkImageFilter.

traversal which respects the CropRect. This is useful when
you want the device-space bounds of a primitive after
filtering. (This may also eventually subsume
computeFastBounds()).
This CL generalizes filterBounds() and onFilterBounds() to
take a mapping direction. It also makes filterBounds()
responsible for calling onFilterNodeBounds() and applying
the crop rect, simplifying onFilterBounds().

Path measure cannot use the same code approach for quadratics
and cubics. Subdividing cubics repeatedly does not result in
subdivided t values, e.g. a quarter circle cubic divided in
half twice does not have a t value equivalent to 1/4.
Instead, always compute the cubic segment from a pair of
t values.
When finding the length of the cubic through recursive measures,
it is enough to carry the point at a given t to the next
subdivision.

If the input bitmap passed to SkTileImageFilter does not fill the
srcRect, we were tiling this incorrectly (see the first sample
from tileimage filter -- it draws from a srcRect of 12,12 50x50
to a dstRect of 0,0 50x50. There should be no tiling at all
in this case!)
In order to fix this, we need to pad the bitmap out to srcRect,
and tile with that. In order to tile correctly in the GPU case,
we need to request a tileable texture.
NOTE: this will change the results of the tileimagefilter GM (correctness,
and added src / dest rects).

It seems that MSVC + __vectorcall don't play well together,
so back ourselves out into a situation where we don't need it.
- Inline transfermode functions. This removes the need for SK_VECTORCALL.
- Remove 565 destination specializations.
Blending into 565 is not speed-critical enough to merit the code bloat.
- Removing 565 specializations means a bunch of Sk4px code is now dead.
8888 xfermodes generally speed up a bit from inlining, smoothly ranging from no change down to 0.65x for the fastest functions like Plus or Modulate.
565 xfermodes generally slow down because we're doing 565 -> 8888 and 8888->565 conversion serially[1] and using the stack, smoothly ranging from no change up to 2x slower for the fastest functions like Plus and Modulate.
[1] the 565->8888 conversion is actually being autovectorized

SkTLogic.h to use the std:: equivelents. This change only uses C++11

Prime motivator:
- we always call refEncoded on the generator when trying to upload
- we call it *before* we ask for raster or YUV
- for blink, this call can be very slow, as they have to cons-up their SkData the first time (and grab a mutex to do it)
- this parameter will indicate to them that we're only interested in gpu formats, which they will know if they have.

There is memory leak in the SkImageFilter::Cache. There are two sources
of memory leak:
1. The cache filling up quickly.
2. A slow small leak that never stops.
This CL solves the first issue, which prevents the cache filling up quickly.
This CL creates a new hash table that index the
SkImageFilter::uniqueID to an array of keys, and with the existing
key<-->Value hash table, we can have SkImageFilters proactively
purge content derived cached content when destroyed.

Make each filter responsible for expanding its destination
bounds. Previously, we were using a union of all
intermediate bounds sizes via join() calls in many image
filters' computeFastBounds(), due to the fact that those
filters could only produce bitmaps the same size as their
inputs. Now, we compute optimal bounds for each filter as
follows:
1) Pass the (unmodified) clip bounds to the root node
of the DAG in the first recursive call to onFilterImage()
as the Context's fClipBounds.
2) Reverse-map the clip: when recursing up the DAG in
filterInput[GPU](), apply filter-specific expansion to the
clip by calling calling onFilterNodeBounds(... kReverse).
This allows upstream nodes to have a clip that respects the
current node's requirements. This is done via helper
function mapContext().
3) Forward-map the source bitmap: just prior to applying
the crop rect in applyCropRect(), we determine the filter's
preferred bounds by mapping the source bitmap bounds
forwards via onFilterNodeBounds(..., kForward).
NOTE: GMs affected by this change:
fast_slow_blurimagefilter: fast and slow paths now produce the same result
spritebitmap: drawSprite() and drawBitmap() paths now produce the same result
filterfastbounds: fast bounds are optimized; all drop-shadow results now appear

It's undefined behavior to pass null as src or dst to memcpy, even if len is 0.
This currently triggers -fsanitize=attribute-nonnull warnings, but also can
lead to very unexpected code generation with GCC.
sk_careful_memcpy() checks len first before calling memcpy(),
which prevents that weird undefined situation.
This allows me to mark all sanitizers as no-recover, i.e. make-the-bots-red fatal.

If the stream can peek less than requested, peek that amount. Return
the number of bytes peeked.
This simplifies crrev.com/1472123002. For a stream that is smaller than
14 bytes, it can successfully peek, meaning the client will not need to
fall back to read() + rewind(), which may fail if the stream can peek
but not rewind.
This CL revives code from patch set 3 of crrev.com/1044953002, where I
initially introduced peek() (including tests).
Add a test for SkFrontBufferedStream that verifies that peeking does
not make rewind() fail (i.e. by reading past the internal buffer).

Because the convolution kernel is (currently) applied in device space,
there's no way to know which object-space pixels will be touched. So
return false from canComputeFastBounds().
The results from the matrixconvolution GM were actually wrong, since
they were showing edge differences on the clip boundaries, where they
should really only show on crop boundaries. I added a crop to the GM
to keep the results the same (which are useful to test the different
convolution tile modes).
While I was at it, SkImageFilter::affectsTransparentBlack() was
inapplicable on most things except color filters, and its use on
leaf nodes was confusing. So I removed it, and made
SkImageFilter::canComputeFastBounds() virtual instead.

Reason for revert:
Introduced memory leak; pixel changes in Chrome.

Because the convolution kernel is (currently) applied in device space,
there's no way to know which object-space pixels will be touched. So
return false from canComputeFastBounds().
The results from the matrixconvolution GM were actually wrong, since
they were showing edge differences on the clip boundaries, where they
should really only show on crop boundaries. I added a crop to the GM
to keep the results the same (which are useful to test the different
convolution tile modes).
While I was at it, SkImageFilter::affectsTransparentBlack() was
inapplicable on most things except color filters, and its use on
leaf nodes was confusing. So I removed it, and made
SkImageFilter::canComputeFastBounds() virtual instead.

This class allows a client of SkCodec to read chunks in the data
stream that are not recognized by libpng. This is used by Android
to specify ninepatch data.
Taken from SkImageDecoder::Peeker. Modify the name of the class
and its method to be more specific to their use. Make
SkImageDecoder::Peeker a subclass of the new class, to help stage
the change in Android.
Add a test to verify that it works.

There may be other (better?) ways to enable this. For example, if we queried the device *before* we init our root DeviceCM, we wouldn't need this flag in InitFlags, since the device already has a virtual to opt-in ...

The new key for the distance field path cache will contain an
SkStrokeRec. This change guarantees that we don't have any hidden
padding that has garbage values, thereby preventing apparently
equal keys from hashing to two different values. This also has
the nice effect of reducing the size of SkStrokeRec from 24 bytes
to 16 bytes.

Add helper to track when a round rect was added to a path,
and then return the SkRRect specification that describes it.
Move the implementation for SkPath::RawIter to SkPathRef so it can be used there as well.

DebugWriteToStderr isn't defined for Android. I'm not sure if I just didn't test compiling for Android or if this is due to a change in the base library.

Extend the SkPath API to allow specifying the contour starting point.
This will allow removing the explicit cubic code from Blink/Path.
