Currently the SkStrikeClient is designed to pull fonts from the server
on demand, and to pre-fetch a batched request by analyzing the ops using
a SkTextBlobCacheDiffCanvas. This change modifies the design to support
a push based model, where the server pushes fonts required by the client
and sets up the requisite SkGlyphCaches on the client prior to
rasterizing the ops.
This model still relies on the SkTextBlobCacheDiffCanvas for analyzing
the glyphs required for rasterizing an op. The glyph caches required for
raster are locked and missing glyphs to be sent to the client are tracked
by the SkStrikeServer. The embedder can serialize this font data at any
point, but must ensure that this data is deserialized by the
SkStrikeClient at the remote end, before rasterizing any ops analyzed
prior to serialization. Any refs on the caches are released once the
font data is serialized by the server.
The locking of glyph caches relies on the embedder providing discardable
handles. These handles can be created on the server and serialized to be
sent to the client, and map to an instance of SkGlyphCache. This allows
the server to control the lifetime of the caches on the client.

The implicit SkTCopyOnFirstWrite copy-ctor and assignment operator are
incorrect: fObj must point to the local copy, not to the source copy
(when a copy has been made).
Add corrected explicit copy (and move) ctor + assignment operator.
Also add a get() helper to facilitate rawptr access.

The big api level change here is that the getBackendInfo calls now return by value
instead of a pointer. These changes are being made in support of Vulkan so that
the client can update the VkImageLayout on the GrBackendTexture and have that
update get reflected in our internal tracking of the image. This is done by storing
a ref counted GrVkImageLayout object on the GrBackendTexture and the GrVkImage.

This CL clarifies what is going on in the GrDrawOpAtlas and GrAtlasGlyphCache.
For the GrDrawOpAtlas:
At creation time all the allowed pages are created (with their backing GrTextureProxies) but they aren't instantiated.
The GrDrawOpAtlas::instantiate call is called in preFlushCB and allocates any pages known to be needed at the start of flush
GrDrawOpAtlas::addToAtlas is called at flush time and, if a new page is activated, will instantiated it at that time.
During compaction, an unused page will be deInstantiated but its Plots and backing GrTextureProxy will remain alive.
The GrAtlasGlyphCache reflects the changes to the GrDrawOpAtlas
It now carries a GrProxyProvider for when it needs to create an atlas
It passes in a GrResourceProvider* at flush time to allow instantiation.
It does not, yet, allocate that GrDrawOpAtlases it might ever require.

no need to update any time soon).

Android's ImageDecoder API takes as input an arbitrary width and height
to scale the image to. Internally, this uses SkAndroidCodec to sample,
and then (if not a perfect match) scales to the desired size with
drawing.
computeSampledSize is a modified version of what ImageDecoder currently
does to convert from arbitrary dimensions to a sampleSize. Moving it
here allows it to be shared by SkAnimatedImage. The modified version
also corrects two bugs:
- a client using the dimensions returned by getSampledDimensions
previously may have resulted in ImageDecoder decoding to a larger
size and then scaling it. (example found in tests: dog.jpg is
180 x 180. getSampledDimensions(8) returns 23 x 23, but the old
method resulted in using sampleSize of 7 and downscaling the resulting
25 x 25 image.)
- recompute the sampleSize based on the size returned by
getSampledDimensions.

We need to discriminate between nodes whose bounds updates contribute to the dirty
region, and nodes whose bounds changes do not.
E.g. animated shape in a group: the animated shape node bounds should yield damage,
but the ancestor group bounds should not.
To accomplish this, we refine the invalidation state:
1) self invalidation == the node itself was invalidated, and its bounds updates
yield damage.
2) descendant invalidation == the node has some (self-)invalidated descendant,
but its own bounds are not contributing damage.
Also:
* hoist the bounding box invalidation logic into the base class (Node::revalidate)
and update to respect the states described above.
* remove (now-redundant) GeometryNode bbox logic.
* update revalidation methods to return the node bbox instead of void

Some interesting things are starting to fall out already,
like the fact that I needed to add a gamma_dst stage to
be able to draw into gamma-transfer-fn destinations.
I've also had to pass an SkAlphaType through to the linearize
functions so that they can maintain premul invariants. I'm not
sure this is actually a good idea... if you can, please double-
check my logic at SkRasterPipeline.cpp:128?
If it's correct logic, I'm going to need to do it all over the place.
But I imagine you don't do this and somehow get away with it.

Hide SkEncodedInfo
Bug: skia:7353
Bug: skia:6839
This contains information that is not necessary for clients to know. The
Color enum tells the number of components in the input, but this is only
interesting internally (to the SkSwizzler).
Similarly, the Alpha enum differs from SkAlphaType in that it has
kBinary instead of kPremul. This is useful information only internally
for determining whether the SkColorSpaceXform needs to premultiply.
The bitsPerComponent is potentially useful for a client; Android (in
SkAndroidCodec) uses it to determine the SkColorType. Rather than
exposing bitsPerComponent, make SkAndroidCodec a friend so it can
access the SkEncodedInfo. A future change will change SkCodec to
recommend F16 for bitsPerComponent > 8, but that will be more involved;
it was the reason for the revert of this CL.
Switch conversionSupported to use an SkColorType, which is enough info.
Replace the SkEncodedInfo::Alpha field on SkCodec::FrameInfo with an
SkAlphaType.
SkCodec still needs an SkEncodedInfo, so move its header (which is
already not SK_API) to include/private.

Reason for revert: Causing differences in Gold, stemming from the fact that this changes the recommended SkImageInfo for 16 bits-per-component PNG from N32 to F16.
- an F16 bitmap already png-encodes to a 16 bits-per-component PNG, but it does not encode a linear colorspace (possibly a bug?). when we decode this PNG using getInfo(), it fails because it has an F16 color type and non-linear colorspace. (In the encode-srgb-png gm, this results in blank results for F16.) We could correct this on the encoder side, but it seems possible that a 16 bits-per-component PNG could be encoded with a different color space. In that case, we'd want SkCodec to recommend F16/SRGBLinear, but I think we'd want the SkCodec to store the encoded SkColorSpace so that we can Xform between the two. Currently SkCodec only stores one color space, so that will require a refactor.
- When decoding 16-bits-per-component PNGs, we are now decoding them to F16. This shows differences in Gold. The srgb/gpu results now look more like F16. I think this is fine.

This contains information that is not necessary for clients to know. The
Color enum tells the number of components in the input, but this is only
interesting internally (to the SkSwizzler).
Similarly, the Alpha enum differs from SkAlphaType in that it has
kBinary instead of kPremul. This is useful information only internally
for determining whether the SkColorSpaceXform needs to premultiply.
The bitsPerComponent is potentially useful for a client; Android (in
SkAndroidCodec) uses it to determine the SkColorType. Rather than
exposing bitsPerComponent, use it to make the same decision that Android
would have made - 16 bits per component means to set the info to F16. Add
a test that computeOutputColorType behaves as expected.
Switch conversionSupported to use an SkColorType, which is enough info.

This was uncovered by the linked fuzzer issue.
I haven't looked hard at it, but I'd guess it's fuzzed an ICC profile
into one that can't be deserialized, and we get a null in CreateProc().
We could probably restrict the null check to just CreateProc(), but
putting it in Make() and asserting in the constructor feels cozy.

This is mostly dead code.
In order to make it truly dead, we need to opt drawing unpremul images
into SkRasterPipelineBlitter. They had been handled by
SkLinearBitmapPipeline, but can't be draw by SkBitmapProcLegacyShader.
Drawing unpremul images is tested by the GM all_variants_8888, which
gave us trouble last time around (serialize-8888 drew right, 8888 wrong)
but now draws fine. I think this was probably also the root of the
revert, drawing some unpremul image in Chrome's tests somewhere.

After lots of tinkering, this is the smallest test case I've
found to reproduce the bug. Frequently, bitmap b4 will be
cleared to blue, but not contain the oval drawn right before.
Bitmap b5 will contain the oval, so the diff of the two
bitmaps will detect the error.
There may be something else that can be removed, but I
haven't found it.
Interesting note:
In the original version, all surfaces were cleared to
black. When I started trying to change the clear colors to
figure out if we were getting an old surface, the bug went
away. In particular, the first clear color is irrelevant,
but the last three clears must all be the same color. If
any are different, the bug doesn't occur.

(Originally uploaded as 13900.)
Previously, SkPngCodec assumed that the stream only contained one
image, which ended at the end of the stream. It read the stream in
arbitrarily-sized chunks, and then passed that data to libpng for
processing.
If a stream contains more than one image, this may result in reading
beyond the end of the image, making future reads read the wrong data.
Now, SkPngCodec starts by reading 8 bytes at a time. After the
signature, 8 bytes is enough to know which chunk is next and how many
bytes are in the chunk.
When decoding the size, we stop when we reach IDAT, and when decoding
the image, we stop when we reach IEND.
This manual parsing is necessary to support APNG, which is planned in
the future. It also allows us to remove the SK_GOOGLE3_PNG_HACK, which
was a workaround for reading more than necessary at the beginning of
the image.
Add a test that simulates the issue, by decoding a special stream that
reports an error if the codec attempts to read beyond the end.
Temporarily disable the partial decoding tests for png. A larger change
will be necessary to get those working again, and no clients are
currently relying on incrementally decoding PNGs (i.e. decode part of
an image, then decode further with more data).
Include a workaround for older versions of libpng (e.g. 1.2 in
Google3). In older versions, if the row callback is null when the
IDAT header is processed, reading the image will fail. When we see the
IDAT, we save the length and process a recreated IDAT header later,
after the row callback has been set.

LZW blocks or ColorMaps. Instead, mark the position and size, and read

This will save memory in Chromium's use case, which has already
buffered all of its data.
In the case where we *do* need to copy, store it on the SkStreamBuffer.
This allows SkGifImageReader to have simpler code.

Looking at SkSmallAlloc hasn't left me terribly impressed. I think we can replace it with something a lot simpler to work with.
That simpler thing's core would be something like SkFixedAlloc, which allocates objects out of a fixed sized buffer, and cleans them up when done.
If needed, we can wrap that with logic to try to allocate out of an SkFixedAlloc, falling back on mallc() when exhausted.

This allows us to create integer textures and sample them from a GrProcessor's code.
Filtering is limited to NEAREST.
Adds tests for reading/writing pixels, copying, and drawing. These operations are not allowed to convert to fixed/float configs.
Vulkan support is TBD.
