There's little benefit to deduping matrices and regions: they're infrequently
used, and doubly infrequently reused. Their use-weighted byte cost is tiny.
There is some downside to deduping matrices and regions. Even when they're not
used, we prepare dictionaries for deduping them for every picture. Each of
these dictionaries costs 160 bytes, so two unused dictionaries make a big chunk
of the ~1100 bytes it takes to allocate an SkPictureRecord. (~330 come from
parent class SkCanvas, 768 from SkPictureRecord itself, here reduced to 448).
One side benefit of not deduping these guys is that the change weighs -140 lines of code.
It may go without saying, but this breaks the picture format.
Testing: out/Debug/tests && out/Debug/dm (which runs all picture modes by default)

SkBitmap.cpp:
When copyTo calls readPixels, only clone the genID if the resulting
SkPixelRef has the same dimensions as the original. This catches a
bug where copying an SkBitmap representing the subset of an SkPixelRef
(which implements onReadPixels) would result in the copy sharing the
genID. (Thanks to r6710, this case can only happen using setPixelRef,
so the updated GpuBitmapCopyTest checks for that.)
Move some unnecessary NULL checks to asserts.
When copyTo performs a memcpy, only clone the genID if the resulting
SkPixelRef has the same dimensions as the original. This catches a bug
where copying an extracted SkBitmap with the same width as its original
SkPixelRef would incorrectly have the same genID.
Add a comment and assert in deepCopyTo, when cloning the genID, since
that case correctly clones it.
BitmapCopyTest.cpp:
Pull redundant work out of the inner loop (setting up the source bitmaps
and testing extractSubset). Create a new inner loop for extractSubset, to
test copying the result to each different config.
Extract a subset that has the same width as the original, to catch the
bug mentioned above.
Remove the reporter assert which checks for the resulting rowbytes.
Add checks to ensure that copying the extracted subset changes the genID.
GpuBitmapCopyTest:
Create an SkBitmap that shares an existing SkPixelRef, but only represents
a subset. This is to test the first call to cloneGenID in SkBitmap::copyTo.
In this case, the genID should NOT be copied, since only a portion of the
SkPixelRef was copied.
Also test deepCopy on this subset.
TestIndividualCopy now takes a parameter stating whether the genID should
change in the copy. It also does a read back using the appropriate subset.
It no longer differentiates between copyTo and deepCopyTo, since that
distinction was only necessary for copying from/to configs other than 8888
(which are no longer being tested), where copyTo did a read back in 8888 and
then drew the result to the desired config (resulting in an imperfect copy).

This reduces the allocation overhead of a null picture (create, beginRecording(), endRecording) from about 18K to about 1.9K. (There's still lots more to prune.)
SkPictureFlat can exploit the fact that Writer32 is contiguous simplify its memory management. The Writer32 itself becomes the scratch buffer.
Remove lots and lots of arbitrary magic numbers that were size guesses and minimum allocation sizes. Keep your eyes open for the big obvious DUH why we save 16K per picture! (Spoiler alert. It's because that first save we issue in beginRecording() forces the old SkWriter32 to allocate 16K.)
Tests passing, DM passing.

This eliminates any dynamic allocation for hash tables that are never used.
This helps SkPicture, where some tables (SkPaint) are almost always used, but
some rarely (SkMatrix) or never (SkRegion).
This also removes the (as yet unimportant) ability for the hash table to
shrink. This makes resizing harder to reason about, so I'd like to leave it
out until we see a need.

This macro replaces:
SkString str;
str.printf("Foo test Expected %d got %d", x, y);
reporter->reportFailed(str);
with the shorter code:
REPORTF(reporter, ("Foo test Expected %d got %d", x, y));
The new form also appends __FILE__:__LINE__ to the message before calling reportFailed().

To do this, this patch changes the "offset/loc" parameter in filterImage() / onFilterImage() from an inout-param to an out-param only, so that the calling filter can know how much the input filter wants its result offset (and doesn't include the original primitive position). This offset can then be applied to the current filter's crop rect. (I've renamed the parameter "offset" in all cases to make this clear.) This makes the call sites in SkCanvas/SkGpuDevice responsible for applying the resulting offset to the primitive's position, which is actually a fairly small change.
This change also fixes SkTileImageFilter and SkOffsetImageFilter to correctly handle an input offset, which they weren't before. This required modifying the GM's, since they assumed the broken behaviour.
NOTE: this will require rebaselining the imagefiltersgraph test, since it has a new test case.
NOTE: this will "break" the Blink layout tests css3/filters/effect-reference-subregion-chained-hw.html and css3/filters/effect-reference-subregion-hw.html, but it actually makes them give correct results. It should be suppressed on the skia roll, and I'll rebaseline it.

These flatten/unflatten function pointers were driving me nuts when reading the
generated assembly for this code. We don't need the flexibility of function
pointers here, so let's use templates to make it more manageable. You'll
notice we get much better typing now on flatten/unflatten.

This works in a way that is similar to SkData.
SkMallocPixelRef::NewWithProc
Motivation: Chrome has a ETC1PixelRef which calls delete[] on the
pixles on destruction. There is no reason for them to almost
duplicate our class, when we can provide them a more flexible
class. Example use:
static void delete_uint8_proc(void* ptr, void*) {
delete[] static_cast<uint8_t>(ptr);
}
SkPixelRef* new_delete_pixref(const SkImageInfo& info,
SkColorTable* ctable) {
size_t rb = info.minRowBytes();
return SkMallocPixelRef::NewWithProc(
info, rb, ctable,
new uint8_t[info.getSafeSize(rb)],
delete_uint8_proc, NULL);
}
SkMallocPixelRef::NewWithData
Motivation: This allows up to eliminate SkDataPixelRef. We
modified SkImage_Raster to use MallocPixelRef rather than
SkDataPixlRef.
Also: Unit tests in tests/MallocPixelRefTest.

Motivation: We want to remove redundant classes from Skia. To
that end we want to remove SkImageRef and its subclasses and
replace their uses with SkDiscardablePixelRef +
SkDecodingImageGenerator. Since Android uses SkImageRef, we need
to make sure that SkDecodingImageGenerator allows all of the
settings that Android exposes in BitmapFactory.Options.
To that end, we have created an Options struct for the
SkDecodingImageGenerator which lets the client of the generator set
sample size, dithering, and bitmap config.
We have made the SkDecodingImageGenerator constructor private
and replaced the SkDecodingImageGenerator::Install functions
with a SkDecodingImageGenerator::Create functions (one for
SkData and one for SkStream) which now take a
SkDecodingImageGenerator::Options struct.
Also added a ImageDecoderOptions test which loops through a list
of sets of options and tries them on a set of 5 small encoded
images.
Also updated several users of SkDecodingImageGenerator::Install to
follow new call signature - gm/factory.cpp, LazyDecodeBitmap.cpp,
and PictureTest.cpp, CachedDecodingPixelRefTest.cpp.
We also added a new ImprovedBitmapFactory Test which simulates the
exact function that Android will need to modify to use this,
installPixelRef() in BitmapFactory.
