90798529a0 clamp to 1.0f in sk_linear_to_srgb_needs_round()
It's awkward today that it can go a little over 1.0f.
This is already slow, so a clamp won't slow it signficantly.

efcc41805b Explicitly fail read/writePixels in invalid color space scenarios
It's not well defined what to do when moving from a nullptr color space to
a tagged destination (drawing, reading, writing, etc...). In these
scenarios, at least, we can choose to disallow the operation (rather than
produce an unexpected or inconsistent result).

  - they may want instead to be libapp.so on Android.

I plan to follow up to make test_apps push themselves to an Android device when a new argument android_serial is set.

56770752c2 -Fast bot upgrades
- GCC -> Clang;
  - Add a Perf bot.

This -Fast mode is a stand-in for "how clients should/do really release code".  Today everyone uses Clang, so we should probably switch this bot too.

I also got interested in how it compares in performance to our ordinary Release build, so I've added a Perf bot.

I did try turning on link-time optimization (much slower build, somewhat faster binary), but that failed at the link step.  Going to save that for later.

464e6a1b5a Retry trim another instruction off SkRasterPipeline overhead
This time, with manual program memory management instead of std::vector<void*>.

Using STL types from SkOpts_hsw.cpp is not safe.  Things like std::vector<void*>
are inlined but not anonymous, so they're deduped by the linker arbitrarily.  This
is bad when we pick the version compiled with AVX instructions on a machine that
doesn't support AVX...

std::vector<Stage> was safe before because Stage itself was anonymous.  While not anonymous, std::vector<Stage> is unique to the compilation unit, because you can only refer to the anonymous Stage in the compilation unit.

8bc9f7b328 Remove SkImageShader -> SkColorShader optimization.
It's turned out to be surprisingly subtle to make the optimization colorspace
correct (it's not today, but with this CL the affected images become colorspace
correct).

Before implementing a colorspace correct color shader, let's check we really need this.

Update: I should say, it's hard to do this optimization and make the resulting color shader be both colorspace correct and "legacy correct".  SkColorShader and SkColor4fShader are both colorspace correct.  It's just challenging to create one shader that's correct for both modes from an image.

2f4686fa25 Quality and performance fixes for AA tessellating path renderer.
Use quads rather than triangles for the edge geometry. This allows
us to perform a simpler edge categorization (see below). It also
improves performance by reducing the number of edges processed during
the simplify and tessellate steps.

Label AA edges as three types: inner, outer, and connector. This
results in correct alpha values for intersected edges, even when
the top or bottom vertex has been merged with a vertex on edges
of different types.

Changed the "collinear edges" sample from the concavepaths GM for a
"fast-foward" shape, which more clearly shows the problem being fixed
here. (The collinearity from the "collinear edges" was actually being
removed earlier up the stack, causing the path to become convex and
not exercise the concave path renderers anyway.)

NOTE: this will cause changes in the "concavepaths" GM results, and
minor pixel diffs in a number of other tests.

b0b625b796 GIF: Better check for frame dependency
If a frame does not have a valid transparent index and it covers the
prior frame, it does not really depend on that frame. Instead, it
depends on the frame that the prior frame depends on.

Determine this once we have parsed the local color map (if any), so a
transparent index out of range of the color map is not considered
valid.

Share code that determines whether a frame has a transparent pixel.

Add a test that we compute the dependencies correctly. randPixelsAnim.gif
has 13 frames. After the first, the frames cover all combinations of

- Whether the prior frame was keep, restoreBG or restoreToPrevious
- Whether the new frame covers the prior frame
- Whether the new frame has a transparent pixel

(It only does so when using a global color table. It may make sense to
expand the test to also cover using local color tables.)

The test caught a bug where we incorrectly reused an existing
SkColorTable for a different frame. Fix that bug by keeping track of
the transparent index associated with the current SkColorTable.

e61c40707e trim another instruction off SkRasterPipeline overhead
The overhead of a stage today is 3 x86 instructions, typically looking something like this:
   - movq (%rdi), %rax  // Load the next stage function pointer.
   - addq $0x10, %rdi   // Step our progress ahead 16 bytes to that next stage.
   - jmpq *%rax         // Transfer control to that stage.

But if we make sure the pointer's in esi/rsi, we can use lodsd/lodsq to do those first two steps in one instruction:
   - lodsq (%rsi), %rax    (≈ movq (%rdi), %rax; addq $0x8, %rsi).
   - jmpq *%rax

This CL rearranges things so that we can take advantage of this and generally trim off an instruction of overhead.  Instead of a vector of {Fn, ctx} pairs, we'll flatten it down into a single interlaced program vector of void*, basically just ommitting any null context pointers.  We pass the pointer to program as the second argument to Fn, putting it in rsi.  These two changes together make getting the next Fn to call or the current context the same cheap lodsq instruction, encapsulated as load_and_increment().

Here's how the simple "modulate" blend stage changes:

    vmulps  %ymm4, %ymm0, %ymm0
    vmulps  %ymm5, %ymm1, %ymm1
    vmulps  %ymm6, %ymm2, %ymm2
    vmulps  %ymm7, %ymm3, %ymm3
    movq    (%rdi), %rax
    addq    $0x10, %rdi
    jmpq    *%rax

    ~~~~~~~~>

    vmulps  %ymm4, %ymm0, %ymm0
    vmulps  %ymm5, %ymm1, %ymm1
    vmulps  %ymm6, %ymm2, %ymm2
    vmulps  %ymm7, %ymm3, %ymm3
    lodsq   (%rsi), %rax
    jmpq    *%rax

This does make getting the current context a one-time, destructive operation. It's switched from referring to ctx as a void* directly to using ctx() as a thunk that returns a void*.  No stage so far has ever referred to ctx twice, and it all appears to inline, so this seems harmless.  "matrix_2x3" is a good example of what stages that use context pointers end up looking like:

    lodsq   (%rsi), %rax
    vbroadcastss    (%rax), %ymm9
    vbroadcastss    0x8(%rax), %ymm10
    vbroadcastss    0x10(%rax), %ymm8
    vfmadd231ps     %ymm10, %ymm1, %ymm8
    vfmadd231ps     %ymm9, %ymm0, %ymm8
    vbroadcastss    0x4(%rax), %ymm10
    vbroadcastss    0xc(%rax), %ymm11
    vbroadcastss    0x14(%rax), %ymm9
    vfmadd231ps     %ymm11, %ymm1, %ymm9
    vfmadd231ps     %ymm10, %ymm0, %ymm9
    lodsq   (%rsi), %rax
    vmovaps %ymm8, %ymm0
    vmovaps %ymm9, %ymm1
    jmpq    *%rax

We can't do this with MSVC, as there's no intrinsic for it I can find, and they disallow inline assembly, and rsi is not used to pass arguments to functions there anyway.  ARM doesn't need it... it does this in two instructions naturally anyway.  We could do this for 32-bit x86 but I'd just rather focus on x86-64.

It's unclear to me that this makes things any faster, but doesn't appear to make things any slower, and makes I think both the code and disassembly simpler.
