This change address what happens when a jpeg is partially downloaded
before failing. Many browsers will render it anyway: we want Skia to
do the same. The JpegTest takes a perfectly cromulent jpeg file and
only passes into the ImageDecoder the first half of the image. We
then verify that the image decoder returns a valid bitmap of the
correct dimensions.
We also fixed some png library errors, including issue 1691.
Also, suppressed the majority of warnings from using libpng and
libjpeg. By default, most warnings are *not* suppressed in debug mode.
If you have a debug binary and wish to suppress warnings, set the
following environment variables to true
skia_images_png_suppressDecoderWarnings
skia_images_jpeg_suppressDecoderWarnings
or from within a program that links to Skia:
#if defined(SK_DEBUG)
#include "SkRTConf.h"
SK_CONF_SET("images.jpeg.suppressDecoderWarnings", true);
SK_CONF_SET("images.png.suppressDecoderWarnings", true);
#endif
I tested this, before (control) and after these changes (test), on
364,295 skps from the cluster telemetry.
- number of errors+warnings in control = 2804
- number of errors+warnings fixed = 2283
- number of PNG verbosity fixed = 2152
- number of PNG error fixed = 4
- number of PNG segfault fixed = 3
- number of PNG errors changed to warnings = 62
- number of JPG verbosity fixed = 26
- number of JPG error fixed = 91
Not all errors and warning have been fixed.
These numbers were generated using the find_bad_images_in_skps.py
program. This program may be useful going forward for testing
image-decoding libraries on skp files from the cluster telemetry.
find_bad_images_in_skps.py depends on the test_image_decoder program,
which simply executes the SkImageDecoder::DecodeFile function and uses
its exit status to report success or failure.

SkDebugCanvas & friends are useful beyond the Qt debugger app - Chromium's picture inspector (in development) is at the point where it could take advantage of it.
This patch moves SkDrawCommand, SkDebugCanvas & SkObjectParser from trunk/debugger to trunk/src/utils (since several tools already use these, this seems appropriate), and makes SkDrawCommand & SkDebugCanvas' symbols visible externally (SK_API).

SkImage calls functions on SkImageDecoder and SkImageEncoder. This
is desired behavior, and it is also desired to include SkImage as
a part of core. In order to keep core from depending on images,
update SkImageDecoder_empty.cpp to implement all of SkImageDecoder
and SkImageEncoder. This file will be built by chrome (in
https://codereview.chromium.org/15960015).
Move force_linking from SkImageDecoder.cpp to its own file. It must
be called to force linking with the image decoders if desired. Call
the function in tools that need it:
sk_image
render_pictures
render_pdfs
sk_hello
filter
bench_pictures
debugger
SkImageDecoder:
Derive from SkNoncopyable, instead of duplicating its
hiding of constructors.
skhello:
Return rather than trying to write a null SkData to the stream.
Revert "Hamfistedly removed core dependence on images"
(commit 0f05f682a90bc125323677abf3476e1027d174f5) and
"Move SkImage::encode to SkImage_Codec.cpp."
(commit 83e47a954d0bf65439f3d9c0c93213063dd70da3.)
These two commits were temporary fixes that this change
cleans up.
SkSnapshot.cpp:
Check for a NULL encoder returned by SkImageEncoder::Create.

Allow passing files or folders on the command line.
Group the output to show all successes together, all failures
together, etc.
When writing a new png, do not make its file type ".png.png"
if the original was a png.
Force linking for JPEG decoder.
Use SkCommandLineFlags.

Make flag parser its own project. It is still in the tools folder,
but can now be used by other projects.
Some changes to behavior in order to work with SkFlags:
enable-missing-warning and disable-missing-warning have become
enableMissingWarning and noenableMissingWarning.
exclude-config is now excludeConfig
--config now can only be listed once, but all configs listed
after it will be included (same with excludeConfig and match).
In addition, writeJsonSummary has been changed to
writeJsonSummaryPath for consistency with other path flags.
Provide an option to SkFlags to provide a short name, and use
it for the flags which have short names.
--tileGridReplayScales now takes space separated arguments,
like other inputs.

SkPurgeableImageCache:
New image cache that uses virtual memory to store the pixels. Combines
features of SkAshmemImageCache (which has been removed) with SkPurgeableMemoryBlock, which has android and Mac versions.
SkImageCache:
Modified the API. pinCache now returns a status out parameter which
states whether the pinned memory retained the old data. This allows
allocAndPinCache to only be used for allocations.
Add a new debug only interface to purge unpinned data.
Updates to documentation, clarifying behavior.
Changed CachedStatus to MemoryStatus
SkLruImageCache:
Implement the new function purgeAllUnpinnedCaches and change implementation
of pinCache for the new behavior.
SkLazyPixelRef:
Rewrite onLockPixels to account for the new behavior of pinCache.
BitmapFactoryTest:
Test the new SkPurgeableImageCache.
Write tests which directly test the SkImageCaches.
Create a larger bitmap, since some of the SkImageCaches are designed
to handle large bitmaps.
bench_ and render_pictures:
Consolidate lazy_decode_bitmap into one function.
Allow using a flag to specify using the purgeable image cache.
Clean up some #includes.

Share common code between bench_ and render_ to set up the PictureRenderer.
Fix an include error in SkPictureRenderer.h.
Simplified parameter passing in render_pictures_main.
Switch to using an SkAutoTUnref for the PictureRenderer.
I also changed the input format somewhat, so the buildbots need to be updated as well: https://codereview.appspot.com/7441044/
Fixed a bug in PictureBenchmark where calling setTimeIndividualTiles(false) sets the member variable to true.
Removed setDeviceType from PictureBenchmark, since only the PictureRenderer needs to know which device type to use.
Some changes to the input format:
'--logPerIter' no longer takes a 1 or 0. Instead, '--logPerIter'
turns it on and '--nologPerIter' turns it off (with off as the
default). (Note that this is for bench_pictures; bench still uses the old format)
Change '--device' to '--config' and 'bitmap' to '8888' to be
the same as gm.
Requires '--r' before inputs (to match gm), though there can be multiple inputs following it.
Changed --enable-deferred-image-decoding (which no one uses but me yet anyway) to --deferImageDecoding, since the former is incompatible with the flag parser.
Changes to behavior:
Show a short error message on failure (rather than the explanation of all
flags).
