a4083c97d4 make most of SkColorPriv.h private
created new file src/core/SkColorData.h for
internal consumption. Note that many of the
functions there are unused as well.

1e114f1368 *SkTCast<int*>(float*) -> memcpy
In some build configurations (I think, GN, GCC 6, Debug) I get a warning that i is used unintialized.  This likely has something to do with GCC correctly seeing that the SkTCast construction there is illegal aliasing, and perhaps thus "doesn't happen".  Might be that if the SkTCast gets inlined, it decides its implementation is secretly kosher, and so Release builds don't see this.  None of this happens with the GCCs we have on the bots... too old?

Instead use memcpy() here, which is well defined to do what we intended.

785a5b941a Clean up SkFloatBits
- remove dead code
- rewrite float -> int converters

The strategy for the new converters is:
   - convert input to double
   - floor/ceil/round in double space
   - pin that double to [SK_MinS32, SK_MaxS32]
   - truncate that double to int32_t

This simpler strategy does not work:
   - floor/ceil/round in float space
   - pin that float to [SK_MinS32, SK_MaxS32]
   - truncate that float to int32_t

SK_MinS32 and SK_MaxS32 are not representable as floats:
they round to the nearest float, ±2^31, which makes the
pin insufficient for floats near SK_MinS32 (-2^31+1) or
SK_MaxS32 (+2^31-1).

float only has 24 bits of precision, and we need 31.
double can represent all integers up to 50-something bits.

An alternative is to pin in float to ±2147483520, the last
exactly representable float before SK_MaxS32 (127 too small).

Our tests test that we round as floor(x+0.5), which can
return different numbers than round(x) for negative x.
So this CL explicitly uses floor(x+0.5).

I've updated the tests with ±inf and ±NaN, and tried to
make them a little clearer, especially using SK_MinS32
instead of -SK_MaxS32.

I have not timed anything here.  I have never seen any of these
methods in a profile.

3361471a35 Simplify benchmark internal API.
I'm not quite sure why I wrote such a convoluted API with setLoops()/getLoops().
This replaces it with a loops argument passed to onDraw().

This CL is largely mechanical translation from the old API to the new one.
MathBench used this->getLoops() outside onDraw(), which seems incorrect.  I
fixed it.

644629c1c7 Implement a benchmark for GrResourceCache
Adds "grresourcecache_add" and "grresourcecache_find" bench tests to test
GrResourceCache::add and GrResourceCache::find. The tests work only
with GPU backends, since GrResourceCache needs an GrGpu.

Modifies bench tests to override SkBenchmark::isSuitableFor(Backend)
function that specifies what kind of backend the test is inteded
for. This replaces the previous "fIsRendering" flag that would
indicate test that did no rendering.

Adds SkCanvas::getGrContext() call to get the GrContext that the
canvas ends up drawing to. The member function solves a common
use-case that is also used in the benchmark added here.
