- Update SkCodec's dox to point out that some of the data must be
read twice in order to decode
- Add an accessor that reports how much is needed for reading twice
- Make SkCodec default to use peek()
If an input stream supports peek()ing, peek() instead of reading.
This way the stream need not implement rewind()
- Make SkCodec use read() + rewind() as a backup
So that streams without peek() implemented can still function
properly (assuming they can rewind).
- read everything we may need to determine the format once
In SkCodec::NewFromStream, peek()/read() 14 bytes, which is enough
to read all of the types we support. Pass the buffer to each subtype,
which will have enough info to determine whether it is the right
type. This simplifies the code and results in less reading and
rewinding.
- NOTE: SkWbmpCodec needs the following number of bytes for the header
+ 1 (type)
+ 1 (reserved)
+ 3 (width - bytes needed to support up to 0xFFFF)
+ 3 (height - bytes needed to support up to 0xFFFF)
= 8
- in SkWebpCodec, support using read + rewind as a backup if peek does
not work.
A change in Android will add peek() to JavaInputStreamAdapter.

If the stream can peek less than requested, peek that amount. Return
the number of bytes peeked.
This simplifies crrev.com/1472123002. For a stream that is smaller than
14 bytes, it can successfully peek, meaning the client will not need to
fall back to read() + rewind(), which may fail if the stream can peek
but not rewind.
This CL revives code from patch set 3 of crrev.com/1044953002, where I
initially introduced peek() (including tests).
Add a test for SkFrontBufferedStream that verifies that peeking does
not make rewind() fail (i.e. by reading past the internal buffer).

The wbmp version of SkImageDecoder will support decoding an image where
the second byte can be masked away with 0x9F. Prior to this CL, SkCodec
checked that the entire byte was zero. The SkCodec implementation
appears to be more correct (at least according to Wikipedia [1]), but
it also means we could regress if someone was using an image that did
not quite fit the specification.

Much of the Skia code dealing with clip bounds does not handle
overflow, so if we start doing any math on these rects, the code will
break. Use explicit reasonable values instead.

The crop rect should be applied to the union of the input bounds, not
to the src input's bounds. These are often the same, since the saveLayer
offscreen size is computed as the union of all the required bounds, but
is not correct if the input primitive is not used (e.g., if all inputs
are connected to SkImageSources). But this will change as we
move to more accurate intermediate bounds computations (getting rid of the join() hacks as described in skbug.com/3194).
Since we can't know this without actually processing the inputs,
split SkMergeImageFilter processing into:
- filter all inputs
- applyCropRect to the union'ed bounds
- allocate the destination
- do the merge

Remove GrContextFactory::getGLContext, it is problematic:
It has the bug of not checking for the context type.
It also is error-prone, since the GL context is not made
current, but it is callers may assume it is current.
It is also not used very much.
Clients can use GrContextFactory::getContextInfo.

Simplifying a series of rects with very large bounds
triggers a coincidence bug where, after one of the
intersection points that marks a coincident range
has been deleted, it is referenced.
Both the deletion and reference is (probably) happening
in the SkOpCoincidence::AddExpanded() phase of
HandleCoincidence(), and may signify a bug that could
happen with usable input data, but I haven't been
able to determine that.
For now, abort the Simplify() when the erroneous
condition is detected.

SkNx_cast() can cast between any of our vector types,
provided they have the same number of elements.
Any types should work with the default implementation,
and we can drop in specializations as needed, like the
SSE and NEON Sk4f -> Sk4i I included here as an example.
To make this work, I made some internal name changes:
SkNi<N,T> -> SkNx<N, T>
SkNf<N> -> SkNx<N, float>
User aliases (Sk4f, Sk16b, etc.) stay the same.
We can land this first (it's PS1) if that makes things easier.

Add support for feeding the tests with contexts directly to the unit
test framework.
This fixes the problem where tests are more complex than needed just in
order to run the test code with multiple backends.
Also makes it possible to change the logic how contexts are
created. Instead of direct numbering, the different testable contexts
may be generated from filtered cross-product of context options. For
example: currently NVPR is a type of context. However, it could be also
an on/off feature of any context. In order to test this kind of context,
the enumeration can not be just of context type. It's simpler
to move the enumeration out of the tests.
A test targeting both normal and GPU backends would look like:
static void test_obj_behavior(skiatest::Reporter* reporter,
SkObj* obj, [other params] ) {
... test with obj and param ..
}
DEF_TEST(ObjBehavior, reporter) {
for (auto& object : generate_object) {
for (auto& other_param : generate_other_variant) {
test_obj_behavior(reporter, object, other_param);
}
}
}
#if SK_SUPPORT_GPU
DEF_GPUTEST_FOR_ALL_CONTEXTS(ObjBehavior_Gpu, reporter, context) {
for (auto& object : generate_gpu_object) {
for (auto& other_param : generate_other_variant) {
test_obj_behavior(reporter, object, other_param);
}
}
}
#endif
