| * | Update some Sk4px APIs. |  mtklein | 2015-06-22 |
| | | | | | | | | | | | | | | | | Mostly this is about ergonomics, making it easier to do good operations and hard / impossible to do bad ones. - SkAlpha / SkPMColor constructors become static factories. - Remove div255TruncNarrow(), rename div255RoundNarrow() to div255(). In practice we always want to round, and the narrowing to 8-bit is contextually obvious. - Rename fastMulDiv255Round() approxMulDiv255() to stress it's approximate-ness over its speed. Drop Round for the same reason as above... we should always round. - Add operator overloads so we don't have to keep throwing in seemingly-random Sk4px() or Sk4px::Wide() casts. - use operator*() for 8-bit x 8-bit -> 16-bit math. It's always what we want, and there's generally no 8x8->8 alternative. - MapFoo can take a const Func&. Don't think it makes a big difference, but nice to do.

| * | Simpler version of Plus w/ AA. ~25% faster too. | mtklein | 2015-05-22 |

| * | Move Sk4px Xfermode code to a header so we can use it twice. | mtklein | 2015-05-22 |
| - Once in SkXfermode as usual to pick up compile-time SSE and NEON - Once in SkXfermode_arm_neon to pick up run-time NEON This allows us to start cleaning up SkXfermode_arm_neon as we've done for SkXfermode_SSE2. I'm saving this catharsis for a day when I need it. The Sk4px xfermodes are generally faster than the existing NEON procs, so this should also have the side effect of a perf win there. This means our new Plus-AA code works for runtime NEON too. BUG=skia:3852 Review URL: https://codereview.chromium.org/1150313003 | |||
