ca5bb87a31 DM: write failed comparison mode .pngs one more level deep in the tree.
E.g.  instead of having to compare
    /tmp/dm/565/optimizations.png
vs.
    /tmp/dm/replay/optimizations_565.png

it's now

    /tmp/dm/565/optimizations.png
vs.
    /tmp/dm/replay/565/optimizations.png

This lets working with skdiff go a lot more smoothly.

7d8013f306 Changes to SkTDStackNester.
SkTDStackNester is a class used by PdfViewer to assist in saving
and restoring the PDF state. Clean up and test this class.

Add some documentation.

Add FIXME's where I have questions to resolve.

Fix a bug where fNestingLevel was not initialized.

Remove a commented out line of code copied over from
SkTDStack.

Rename SkTDStackNester::nests() to nestingLevel() and make it const.

Remove unnecessary predeclaration and friend declaration.

Remove index() (both const and non-const versions). They were
unused, return something that may not be expected (index from
the top, rather than from the bottom), and don't work to get any
elements in earlier Recs once the first one is full.

Report a warning if the nesting level goes above the maximum level,
or if we attempt to bring it below zero.

Prevent fNestingLevel from dropping below zero.

Add kUnusedObject_SkPdfIssue, and use it where appropriate.

1f0121af49 New SkRTConf macro SK_CONF_TRY_SET: no complaint on missing configuration
SK_CONF_TRY_SET() is like SK_CONF_SET(), but doesn't complain if
confname can't be found.  This is useful if the SK_CONF_DECLARE is
inside a source file whose linkage is dependent on the system.

Internally to the SkRTConf system, SkRTConfRegistry::set() was given
an additional parameter controling wanrings.

A new RuntimeConfig unit test was introduced.  It should run silently.
In the future, it should be expanded to cover all of the SkRTConf
functionality.

(For example, the images.jpeg.suppressDecoderWarnings variable is
defined and used only in SkImageDecoder_libjpeg.cpp, but on MacOS, we
use Core Graphics via SkImageDecoder_CG.cpp - SkImageDecoder_libjpeg
is never linked in.  The same is true of the Windows Imaging Component
on Windows.)

commit-bot@chromium.org
6e3e42296b Break up SkLazyPixelRef functionally into class hierarchy.
The reason for this CL is to allow greater decoder flexibility.
Chrome currently uses its own decoding functions.  These allow for
greater flexibility in dealing with images with multiple frames or
partial data.  The DecodeProc function was not flexible enough to
handle these.  Instead of asking the decoder to squeeze everything
into the DecodeProc, we now ask the downstream library to inherit from
SkCachingPixelRef.  If WebKit's LazyDecodingPixelRef is re-tooled to
inherit from SkCachingPixelRef, then it can make use of Skia's caching
ability while still allowing it to deal with multiple frames, scaling,
subsetting, and partial data.

-   The abstract SkCachingPixelRef class handles caching the decoded
    data in a SkScaledImageCache.  This class relies on the virtual
    functions onDecodeInfo() and onDecode() to do the actual decoding
    of data.

-   The SkLazyCachingPixelRef class is derived from SkCachingPixelRef.
    It provides an implementation of onDecodeInfo() and onDecode() in
    terms of calls to a SkBitmapFactory::DecodeProc function.  It also
    provides an Install() static method which installs a new
    SkLazyCachingPixelRef into a SkBitmap.

SkLazyCachingPixelRef exists for two reasons: to test
SkCachingPixelRef within Skia and as an example for downstream
developers to make their own classes that inherit from
SkCachingPixelRef.

-   The CachedDecodingPixelRefTest was updated to test the
    SkLazyCachingPixelRef class and indirectly the SkCachingPixelRef
    class.

d3e5842db0 Avoid re-rendering stencil clip for every draw with reducable clip stack
Fixes the cases where clip stack reduction would cause clip to be
re-rendered to stencil for each draw call. This causes unneeded
slowdown.

Stencil cache would not be used because the clip stack generation id communicated
by the clip stack element list would be invalid. This happended due to

 a) clip stack reduction creating new elements in the element list.

 b) purging logic removing the generation id, but reduction logic
    selecting already purged element, and thus the generation id, as
    the representative state of the clip.

Cases of a) where reduction would flatten the stack to a single new
element were fixed by assigning the generation id of the top-most
element of the clip stack as the generation id of the new
element. This is not strictly minimal, but enables more caching than
using invalid id.

Cases of a) where reduction would substitute a stack element with a
new element the generation id of the substituted element is used.

The b) part was fixed by removing the purging logic. It was not
exactly correct, as the previously purged states were actually
used. The purging was not used for anything.

Changes SkClipStack API to highlight that invalid generation id is
never returned by SkClipStack. Empty stacks are wide open. Changes the
clients to reflect this.

Fixes a crash when not passing anti-alias out parameter to
GrReducedClip::ReduceClipStack. The crash is not exercised in the
current code.

679eb674fc Avoid re-rendering stencil clip for every draw with reducable clip stack
Fixes the cases where clip stack reduction would cause clip to be
re-rendered to stencil for each draw call. This causes unneeded
slowdown.

Stencil cache would not be used because the clip stack generation id communicated
by the clip stack element list would be invalid. This happended due to

 a) clip stack reduction creating new elements in the element list.

 b) purging logic removing the generation id, but reduction logic
    selecting already purged element, and thus the generation id, as
    the representative state of the clip.

Cases of a) where reduction would flatten the stack to a single new
element were fixed by assigning the generation id of the top-most
element of the clip stack as the generation id of the new
element. This is not strictly minimal, but enables more caching than
using invalid id.

Cases of a) where reduction would substitute a stack element with a
new element the generation id of the substituted element is used.

The b) part was fixed by removing the purging logic. It was not
exactly correct, as the previously purged states were actually
used. The purging was not used for anything.

Changes SkClipStack API to highlight that invalid generation id is
never returned by SkClipStack. Empty stacks are wide open. Changes the
clients to reflect this.

Fixes a crash when not passing anti-alias out parameter to
GrReducedClip::ReduceClipStack. The crash is not exercised in the
current code.

2bd8b81005 move SkImage::ColorType into SkColorType
objective -- move clients over to SkImage

tasks
- use SkImageInfo instead of SkBitmap::Config
- add support for colortables to SkImage
- add drawImage to SkCanvas
- return SkImage from readPixels

This CL works towards the first task

0251288112 Adding size parameter to read array functions
In some cases, the allocated array into which the data will be read is using getArrayCount() to allocate itself, which should be safe, but some cases use fixed length arrays or compute the array size before reading, which could overflow if the stream is compromised.

To prevent that from happening, I added a check that will verify that the number of bytes to read will not exceed the capacity of the input buffer argument passed to all the read...Array() functions.

I chose to use the byte array for this initial version, so that "size" represents the same value across all read...Array() functions, but I could also use the element count, if it is preferred.

Note : readPointArray and writePointArray are unused, so I could also remove them
