e7fc14b55b Move all knowledge of X sampling into SkScaledCodec
Prior to this CL, each SkCodec subclass that allows sampling does an
extra check in onStartScanlineDecode to determine whether the X dimension
is supported for sampling. Remove this check, and provide a way for
SkScaledCodec to directly access the SkSwizzler, and update it to do
sampling. This way, the SkCodec knows nothing of sampling, but we can
still save the extra step of sampling afterwards.

FIXME: SkBmpRLECodec still calls SkScaledCodec::DimensionsSupported. It
seems like it could directly support sampling, rather than dealing with
SkScaledCodec (partially).

Add a new base class for SkSwizzler. It allows updating the swizzler
after it was created, which is done by SkScaledCodec. Modify SkSwizzler's
constructor/factory function to stop taking any info about sampling,
assume the sample size is one, and move modifying that into a virtual
function overridden from the base class.

7a14b310d6 SkPDF: Implement drawImage*() properly
drawImage calls now properly embeds the original jpeg.

NOTE: drawBitmap*() calls no longer embed JPEG files when
possible (this is in advance of eliminating bitmaps backed
by encoded data).  Chromium has already moved from
drawBitmap to drawImage.

Comparisons:

control:
    total PDF drawImage/drawBitmap calls: 8010
    total PDF jpeg images: 0
    total PDF regular images: 3581

experiament:
    total PDF drawImage/drawBitmap calls: 8014
    total PDF jpeg images: 271
    total PDF regular images: 3311
    total PDF regular images: 3582 (271 + 3311)

When comparing rendered output there were perceptual
differences in the following four GMs: colorcube, emboss,
colormatrix, and tablecolorfilter.  All of these differences
were improvements (that is, closer to the 8888 rendering)
due fixing a bug with colorfilters and forgetting to call
notifyPixelsChanged.

No SKPs had perceptual differences.

Total PDF size dropped from 133964 kB to 126276 kB, a 5.7%
improvement (mostly due to restoring use of JPG images in
SKPs).

7fac5af5e9 Fix bug testing SkCodec for ICO
Looking in Gold, I see some ICO images that only show the upper left
corner of the originals. It is happening because we use different ways
of deciding what the dimensions are:

In CodecSrc::size(), we use an SkScaledCodec to get the dimensions,
even when fMode is not kScaledCodec_Mode.

In CodecSrc::draw(), we only use SkScaledCodec in kScaledCodec_Mode.

My recent CL to combine SkScanlineDecoder with SkCodec revealed this
bug, because now SkScaledCodec::NewFromStream will succeed on ICO.
(Previously, it failed because we do not yet have a scanline decoder
for ICO (skbug.com/4404). Now that they are combined, we would need
to specially flag ICO to stop returning an SkScaledCodec.)

Switch size() to use the correct type of codec.

56c6a117b2 CMake for Windows
Except for some small edits, this is mainly:

patch from issue 1353953004 at patchset 80001 (http://crrev.com/1353953004#ps80001)

CMake configuration file for compiling Windows x64 VS2013 with CMake.

Things to be fixed:
- only x64 is supported
- I didn't try SKIA_GDI (experimental) and directly went for the DirectWrite - this should need an option in the CMake configuration
- make sure yasm and custom build rules paths are set correctly - if the hierarchy changes CMake will just blow things up
- compilation works but there are LOTS and LOTS of warnings (over 9000), if this is okay nevermind but since most of them are related to deprecated functions either consider fixing or suppressing them
- Release mode is untested - I suppose it won't be a big deal but might need some fixing

46c5747256 Merge SkCodec with SkScanlineDecoder
Benefits:
- This mimics other decoding APIs (including the ones SkCodec relies
on, e.g. a png_struct, which can be used to decode an entire image or
one line at a time).

- It allows a client to ask us to do what we can do efficiently - i.e.
start from encoded data and either decode the whole thing or scanlines.

- It removes the duplicate methods which appeared in both SkCodec and
SkScanlineDecoder (some of which, e.g. in SkJpegScanlineDecoder, just
call fCodec->sameMethod()).

- It simplifies moving more checks into the base class (e.g. the
examples in skbug.com/4284).

BUG=skia:4175
BUG=skia:4284

=====================================================================

SkScanlineDecoder.h/.cpp:
Removed.

SkCodec.h/.cpp:
Add methods, enums, and variables which were previously in
SkScanlineDecoder.
Default fCurrScanline to -1, as a sentinel that start has not been
called.

General changes:
Convert SkScanlineDecoders to SkCodecs.

General changes in SkCodec subclasses:
Merge SkScanlineDecoder implementation into SkCodec. Most (all?) owned
an SkCodec, so they now call this-> instead of fCodec->.

SkBmpCodec.h/.cpp:
Replace the unused rowOrder method with an override for
onGetScanlineOrder.
Make getDstRow const, since it is called by onGetY, which is const.

SkCodec_libpng.h/.cpp:
Make SkPngCodec an abstract class, with two subclasses which handle
scanline decoding separately (they share code for decoding the entire
image). Reimplement onReallyHasAlpha so that it can return the most
recent result (e.g. after a scanline decode which only decoded part
of the image) or a better answer (e.g. if the whole image is known to
be opaque).
Compute fNumberPasses early, so we know which subclass to instantiate.
Make SkPngInterlaceScanlineDecoder use the base class' fCurrScanline
rather than a separate variable.

CodexTest.cpp:
Add tests for the state changes in SkCodec (need to call start before
decoding scanlines; calling getPixels means that start will need to
be called again before decoding more scanlines).
Add a test which decodes in stripes, currently only used for an
interlaced PNG.

a5b0f0318b cmake tweaks
• -w silences all warnings current and future.  We're not using this for development.
  • There's no real need to exclude files in Release mode.
    The linker may whine a little, but that's fine.
  • Quiet down message() calls that run every time.  They're fine if you can figure out
    how to run them only when doing the detection and cache them like all the others,
    but I don't like the noise seeing them every run.
  • cheaders is hard to read.  c_headers.
  • ../src/*mac* erroneously picks up SkLumaColorFilter on non-case-sensitive file systems.
    ../src/*_mac* seems fine.

242397a1c9 Revert of Implement SkImageFilter::Cache with SkResourceCache. (patchset #8 id:140001 of https://codereview.chromium.org/1370323002/ )
Reason for revert:
Landed PS8 temporarily to trigger the perf bots.

Original issue's description:
> Implement SkImageFilter::Cache with SkResourceCache.
>
> The single global cache now uses the global SkResourceCache,
> and any Create()ed cache uses a local SkResourceCache.
>
> No real public API changes (and only deletes).
>
> I don't see any pixel diffs on .skps or GMs.
> Don't see any significant perf difference on 8888 or gpu configs.
> DM peak memory usage did drop by about 113M, close to the 128M cache size.

75135d8ae1 Implement SkImageFilter::Cache with SkResourceCache.
The single global cache now uses the global SkResourceCache,
and any Create()ed cache uses a local SkResourceCache.

No real public API changes (and only deletes).

I don't see any pixel diffs on .skps or GMs.
Don't see any significant perf difference on 8888 or gpu configs.
DM peak memory usage did drop by about 113M, close to the 128M cache size.
