Motivation:
I have downloaded a barebones Linux system built for 64-bit ARM
from linaro.org and a ARMv8 Foundation Model from arm.com to run
it on. This will let us build and test Skia on ARM64 before we
aquire hardware to allow that. This CL introduces the changes to
the build files necessary to build Skia on a barebones embedded
Linux system. I tested it with the aarch64 GCC compiler provided
by linaro.org.
Changes:
Add a "barelinux" target_os for the DEPS file. Add an optional
git download of zlib.
Changes to gyp files: these changes abstract out libpng, libz, and
giflib so that images.gyp doesn't know whether they are static or
dynamically linked. I also add the variables skia_giflib_static,
skia_libpng_static, skia_zlib_static, and skia_freetype_static,
all of which default to false but when set to true will override
the behavior of the giflib, libpng, zlib, and freetype build
targets to require them to build statically. Also, the
skia_no_fontconfig variable turns off use of the fontconfig service.
Scripts in platform_tools/barelinux/bin:
arm64_download - this script downloads the Linaro's ARMv8 Aarch64
toolchain and minimal embedded Linux system as well as ARM's
foundation model. The required files are mirrored on Google
Cloud. The script then starts a emulated Arm64 Linux system in
the background. After the boot is complete, you can SSH into the
system at port 8022 via user@localhost. The SSH key will be
downloaded into the working directery as well.
download_deps - Uses gclient to download Skia's dependencies for a
bare Linux system (the normal dependecies plus giflib, libpng, and
zlib.)
barelinux_make - this script builds a version of skia that does
not depend on external libraries, perfect for putting in an
embedded system running Linux. Assumes you have run download_deps
first.
To test:
To build a barelinux target, use the barelinux_make script.
To build for a armv8 system: skia_arch_type=arm arm_neon=0 armv7=1
armv8=1 arm_thumb=0 skia_arch_width=64 and set the CC and CXX
variables to point at the cross-compiler downloaded by
arm64_download.

Removed SkBitmapFactory since no clients were using it. New cache
selection mechanism can simply pass a SkDiscardableMemory::Factory
into the SkDiscardablePixelRef if non-default SkDiscardableMemory
should be used. Removed BitmapFactoryTest.
SkDiscardableMemory::Factory interface. Android will need this
functionality in the future inside their BitmapFactory.
Removed SkLazyPixelRef, since it's functionality is now subsumed into
SkDiscardablePixelRef. Removed LazyPixelRef test.
Modified SkDiscardablePixelRef to optionally allow it to use a
SkDiscardableMemory::Factory. This tiny change makes it a replacement
for SkLazyPixelRef. This functioanlity is also necessary for moving
Android over to SkDiscardablePixelRef from SkImageRef in a later CL.
Added a test for this.
SkDecodingImageGenerator::Install can optionally pass a factory in to
SkDiscardablePixelRef.
Removed SkImageCache, SkLruImageCache, and SkPurgeableImageCache.
This functionality can be handled much more cleanly by
SkDiscardableMemory.
New SkDiscardableMemoryPool class to replace SkLruImageCache. In a
later CL, we will replace SkImageRef_GlobalPool (used by android) as
well. This is a concrete implementation of
SkDiscardableMemory::Factory. Added a test for this.
modified gm/factory.cpp to remove dependnce on SkBitmapFactory +
SkLruImageCache. Now uses SkDecodingImageGenerator +
SkDiscardablePixelRef + SkDiscardableMemoryPool.
SkImageDecoder::Target replaces SkBitmapFactory::Target. The
DecodeMemoryToTarget function may disappear in the future.
Moved SkLazyCachingPixelRef::DecodeProc replaces
SkBitmapFactory::DecodeProc. This is a short term change, since
another CL changes SkLazyCachingPixelRef to use SkImageGenerator
instead of DecodeProc.
Modified DrawBitmapRectTest to use SkDiscardablePixelRef instead of
SkLazyPixelRef.
tools/LazyDecodeBitmap.cpp now uses SkDecodingImageGenerator +
SkDiscardablePixelRef instead of a SkBitmapFactory.
bench_pictures uses the Global SkDiscardableMemoryPool instead of a
global gLruImageCache.

The following have the same effect on Windows:
'msvs_settings': { 'VCLinkerTool': { 'AdditionalDependencies': [ 'windowscodecs.lib', ],},},
'link_settings': {'libraries': ['-lwindowscodecs.lib',],},
But this one is different:
'link_settings': {'libraries': ['windowscodecs.lib',],},
since this last one will attempt to find the library at
third_party\skia\gyp\windowscodecs.lib
or a place like this, instead of looking in the library paths.
This also fixes capitalization of the affected libraries.

This is a step toward targets declaring their deps in a sane fashion.
This change resolves cycles by forcing core to the root, then everything
in skia_lib pointing toward core as best possible, then everything
outside skia_lib depending on skia_lib for things in skia_lib. This
prevents double definitions where a symbol is provided by both the
skia_lib shared object and and a statically linked component of skia_lib.

This change resolves cycles by forcing core to the root,
then opts, ports, and utils depending on core, then everything else.
We will need some other change to resolve the fact that
core, opts, ports, and utils depend on each other and other targets which
depend on them. Outside of these targets, things look ok.

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.

Previously, each tool that wanted to use image decoders
but did not specifically reference them had to create a
dummy function that references them in order to ensure
they are not stripped by the linker.
Instead of making each tool reference each image decoder,
do it once in SkImageDecoder.cpp. Now each tool will have
image decoders linked in, assuming it includes the images
project.
This fixes a bug where SKPs with encoded data could not
be read by bench_ or render_pictures.

The new pixel ref behaves similarly to SkImageRef, with some key differences:
It does not depend on the images project.
It requires an SkImageCache, which handles allocation and caching of the pixel
memory.
It takes a function signature for decoding which decodes into already allocated
pixel memory rather than into an SkBitmap.
Add two implementations of SkImageCache: SkLruImageCache and SkAshmemImageCache.
Replace SkSerializationHelpers::DecodeBitmap with SkPicture::InstallPixelRefProc,
and update sites that referenced it.
SkBitmapFactory now sets the pixel ref to a new object of the new
class SkLazyPixelRef, provided it has an SkImageCache for caching.
Provide an option to do lazy decodes in render_pictures and bench_pictures.
SkPicture:
Eliminate the default parameters in the constructor.
If a proc for decoding bitmaps is installed, use it to decode any encoded
data in subpictures.
When parsing deserializing subpictures, check for success.
When serializing subpictures, pass the picture's bitmap encoder to the
subpicture's call to serialize.
Update BitmapFactoryTest to test its new behavior.
