13dd023882 Update Android FreeType version.
Update FreeType to a newer version. Because this caused issues in
finding the correct ftoptions.h and ftmodule.h [1], be sure to state
the ones we want explicitly.

This also add gzip.c which is needed for WOFF support [2].

[1] FreeType "Simplify header file hierarchy."
    fae382076409db198dfbff36ac4cbb97b05b30a1

[2] FreeType "[gzip] New function `FT_Gzip_Uncompress'."

87ed6be0e4 Get debugger compiling again
Recent house cleaning has broken the debugger - mainly around the defunct profiling feature. This makes CL it even more defunct.

3c8ceb7350 Simplify linkages to Android framework internals
We've migrated SkHwuiRenderer into the Android Framework as
android::uirenderer::TestWindowContext in response to an internal
bug; we now delete that class and change our build references here.

   - Implement SkTime::GetMSecs() in terms of SkTime::GetNSecs().
   - Delete unused tools/timer code.

imgblur is intended to establish a ground truth for debugging mask blur issues. It performs a brute force (non-separable) Gaussian blur of the provided image.

The blur code itself is in sk_tools_utils so it can be more easily used programmatically in other places (e.g., blur unit tests).

26ad22ab61 Enabling clip stack flattening exercises path ops.
Iterating through the 903K skps that represent the
imagable 1M top web pages triggers a number of
bugs, some of which are addressed here.

Some web pages trigger intersecting cubic
representations of arc with their conic
counterparts. This exposed a flaw in coincident
detection that caused an infinite loop. The loop
alternatively extended the coincident section and,
determining the that the bounds of the curve pairs
did not overlap, deleted the extension.

Track the number of times the coincident detection
is called, and if it exceeds an empirically found
limit, assume that the curves are coincident and
force it to be so.

The loop count limit can be determined by enabling
DEBUG_T_SECT_LOOP_COUNT and running all tests. The
largest count is reported on completion.

Another class of bugs was caused by concident
detection duplicating nearly identical points that
had been merged earlier. To track these bugs, the
'handle coincidence' code was duplicated as a
const debug variety that reported if one of a
dozen or so irregularities are present; then it is
easier to see when a block of code that fixes one
irregularity regresses another.

Creating the debug const code version exposed some
non-debug code that could be const, and some that
was experimental and could be removed. Set
DEBUG_COINCIDENCE to track coincidence health and
handling.

For running on Chrome, DEBUG_VERIFY checks the
result of pathops against the same operation
using SkRegion to verify that the results are
nearly the same.

When visualizing the pathops work using
tools/pathops_visualizer.htm, set
DEBUG_DUMP_ALIGNMENT to see the curves after
they've been aligned for coincidence.

Other bugs fixed include detecting when a
section of a pair of curves have devolved into
lines and are coincident.

e6dd004c1b Fill incomplete images in SkCodec parent class
Rather than implementing some sort of "fill" in every
SkCodec subclass for incomplete images, let's make the
parent class handle this situation.

This includes an API change to SkCodec.h

SkCodec::getScanlines() now returns the number of lines it
read successfully, rather than an SkCodec::Result enum.
getScanlines() most often fails on an incomplete input, in
which case it is useful to know how many lines were
successfully decoded - this provides more information than
kIncomplete vs kSuccess.  We do lose information when the
API is used improperly, as we are no longer able to return
kInvalidParameter or kScanlineNotStarted.

Known Issues:
Does not work for incomplete fFrameIsSubset gifs.
Does not work for incomplete icos.

f174e92873 Update libwebp and resume testing scaled webp
libwebp has a fix for [1]. Update to the commit that contains the fix.

Update libwebp.gypi, corresponding to libwebp's latest makefile.

Turn back on DM testing for scaled webp, now that it should no longer
use uninitialized memory.

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).

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.

TODO: Add tests for onReallyHasAlpha.
