It's been driving me nuts that I can't just write `SkMatrix44 m;`,
and I often don't care whether it's initialized or not. The default
identity constructor would be nice to use, but it's deprecated.
By tagging this constructor deprecated, we're only hurting ourselves;
our big clients disable warnings about deprecated routines and use it
freely.
A quick tally in Skia shows we mostly use the uninitialized constructor,
but sometimes the identity constructor, and there is a spread of all
three in Chromium. So I've left the two explicit calls available.
I switched a bunch of calls in Skia to use the less verbose constructor
where it was clear that it didn't matter if the matrix was initialized.
Literally zero of the kUninitialized constructor calls looked important
for performance, so the only place I've kept is its lone unit test.
A few places read clearer with an explicit "identity" to read.

This is a reland of b8fef7c986
readpixels is now disabled on serialize-8888.
The image encoding means it doesn't quite round trip,
though the image looks fine to the eye.

This time the implementation is still in SkColorSpace.cpp,

We don't support unpremultiplied images. Therefore:
- Don't test unpremul source images.
- After doing an unpremultiplying read, make sure to premul before drawing

SkColorSpaceXform.

Good news:
Everything seems to work as it is supposed to. That's why this
CL is just tests.
Bad news:
Picture is a bit strange in that the caching behavior may affect
how the output looks. Ex: If we choose to cache, we will first
draw into the picture's colorSpace and then convert that to the
dstColorSpace. If we choose not to cache, we will draw directly
into the dstColorSpace.
And then untagged pictures seem like they really shouldn't work
very well... We are caching a legacy draw and then drawing that
into the dstColorSpace? Maybe this isn't the most critical
thing to think about right now though, given Florin's work.
Remaining TODOs:
Color space support for gpu-backed images.
I still plan to clarify conversions that are allowed vs. not
allowed and share that code between all SkImages.
