It appears that CTFontCreateCopyWithAttributes and
CTFontCreateCopyWithSymbolicTraits share similar issues with the default
font on OSX10.10. CTFontCreateWithFontDescriptor cannot be used as
it will not work with webfonts. Since this is all low-level use, create the
CTFonts from the underlying CGFonts directly.

This CL removes the uses of SkNEW that have resprouted since commit
385fe4d, and removes the macros entirely now that Android and Chromium
have been cleaned up to no longer depend on them.
A bunch of files implicitly depend on #include <new> from SkPostConfig.h
still though, so keep that for now. To be fixed in a followup CL.

I spent some time looking at perf.skia.org and it looks like we can do better.
It is weird, weird, weird that on x86, we see three completely different behaviors:
- x86 Android: inlining better for small N, custom better for large N;
- Windows: inlining better for large N, custom better for small N;

libjpeg-turbo turns on dithering by default. When we
decode to RGBA, it uses Floyd-Steinberg dithering -
consistent with the libjpeg6b gold standard,
When we decode to 565, it uses ordered dithering. Ordered
dithering for 565 is not part of the 6b standard (libjpeg6b
doesn't even support 565) and is causing us a number of
issues:
(1) Ordered dithering + nearest neighbor sampling is
causing checkerboard visual artifacts in some outputs.
(2) The ordered dither function in libjpeg-turbo actually
behaves differently depending on the alignment of the
memory that it decodes into. This means that two image
decodes that should be identical may look different just
because they decode into different memory blocks. This
was causing some diffs on Gold with the scanline_subset
test that were causing me some confusion.
(3) Maybe not the best evidence, but visually I can't tell
a difference with and without dithering (except when
nearest neighbor scaling causes the checkerboard artifact).
(4) Turning off dithering should be a more significant
performance improvement than you might expect.
libjpeg-turbo has SIMD color conversions to 565, but when
dithering is on, it defaults to scalar code.
This CL should make every jpeg decode to 565 on Gold look
slightly different. Yay!

Right now we have a bug in Gold where some images are labeled
_0.167 and others are labeled _0.166. They are all 1/6
scales and should be labeled the same way and compared.
The fix involves changing 0.166 to 0.167 in the list of
scales that we test on, but SkScaledCodec does not scale
to 0.167 as I expected.
SkScaledCodec converts 0.167 to sampleSize = 5.999 and then
casts to sampleSize = 5. I would argue that we should do
a true round, so 0.167 represents a sampleSize of 6.
In general, this CL change onGetScaledDimensions so that
we now round desiredScale to the nearest sampleSize.

Previously annotations added between saveLayer/restore were lost.
Merge annotations in SkPDFDevice::drawDevice(). Also modified code to
apply correct transformation and clipping on annotations added between
saveLayer/restore:
- Apply the initial transform only when adding the annotations into the
doc, otherwise we need to unapply sub-device's initial transform
before merging the annotations into parent-device.
- Apply only device-local clipping. fClipStack is in global coordinates,
which is not suitable to clip rects in sub-devices.
