5379051ee7 Fix SkScalerContext_FreeType::generateFontMetrics.
SkScalerContext::generateFontMetrics implementations should not attempt
to take into account skew. This implementation should correctly handle
bitmap fonts as well.

8602ede5fd In the current code, tiling and bilerp sampling are strongly tied together. They can be separated by taking advantage of observation that translating a sample point into filter points in the bilerp stage the filter points will be at most 0.5 outside the tile. This allows simplified repositioning for the various tiling modes; clamp and mirror use min and max while repeat has max -> 0 and 0-> max. This allows bilerp to simply treat the filter points that fall off the tile. This allows tiling and bilerp sampling to be totally separate.
This CL has several parts that are intertwined:
* move pin/wrap functionality into BilerpSampler.
* remove the nearest neighbor and bilerp tilers
* create a simplified general tiler
* remove the pipeline virtual calls bilerpEdge and bilerpSpan because everything works of sample points now.
* redo all the bilerp sampling to use the new local to methods to wrap/pin.
* introduce a new medium rate sample that handles spans with 1 < |dx| < 2.

This change improves the performance as displayed below:
Most of top 25 desktop improves or are the same. A few are worse, but close to the noise floor. In addition, this change has about 3% smaller code.

959d45b433 Miscellaneous color space refactors
(1) Use float matrix[16] everywhere (enables future code
    sharing).
(2) SkColorLookUpTable refactors
    *** Store in a single allocation (like SkGammas)
    *** Eliminate fOutputChannels (we always require 3,
        and probably always will)
(3) Change names of read_big_endian_* helpers

7fbfbbe8f4 Basic standalone GN configs.
This sketches out what a world without Chrome's GN configs would look like.

Instead of DEPSing in build/, we now host our own gypi_to_gn.py.

The symlink from skia/ to . lets us run gclient hooks when the .gclient file is in the directory above skia/ or inside skia/.  That means we don't need gn.py anymore.

f41ae2f973 limit the number of points in SkDashPathEffect::asPoints
If the length of a line path is sufficiently long relative to the dash
interval, it is possible to cause SkDashPathEffect::asPoints to produce
so many points that it overflows the amount that can fit in an int type,
or otherwise produce non-finite values, i.e. path from (0,0) to (0,9e15)
with a dash interval of 1.

This fixes that by capping the amount of points to a sane limit - in this
case, 1mil, since that limit is also used in utils/SkDashPath.cpp and has
precedent.

Fix another fuzzer bug.

Some PathOps asserts only make sense if the incoming data is
well-behaved. Well-behaved tests set debugging state to
trigger these additional asserts.

Formalize this by creating macros similar to SkASSERT that
check to see if the assert should be skipped.

0c902473d6 Correct sRGB <-> linear everywhere.
This trims the SkPM4fPriv methods down to just foolproof methods.
(Anything trying to build these itself is probably wrong.)

Things like Sk4f srgb_to_linear(Sk4f) can't really exist anymore,
at least not efficiently, so this refactor is somewhat more invasive
than you might think.  Generally this means things using to_4f() are
also making a misstep... that's gone too.

It also does not make sense to try to play games with linear floats
with 255 bias any more.  That hack can't work with real sRGB coding.

Rather than update them, I've removed a couple of L32 xfermode fast
paths.  I'd even rather drop it entirely...

e499adf328 Use dFdx in Vulkan to address distance field issues.
On Nexus Player and occasionally Nexus 5x we get transparent boxes around
paths. This appears to be because the dFdy call is not as accurate as
dFdx, which is the opposite of Mali 400. As Mali 400 is not supported with
Vulkan, we can go back to using dFdx in this case.

566ea9b9fc Tune linear->sRGB constants to round-trip all bytes.
I basically just ran a big 5-deep for-loop over the five constants here.
This is the first set of coefficients I found that round trips all bytes.
I suspect there are many such sets.
