* SkUTFGravatar Hal Canary2018-07-31
| | | | | | | | | | | | | | | | | | | | | Create new header and namespace, `SkUTF` where we are putting all of our robust, well documented UTF-8, UTF-16, and UTF-32 functions: `SkUTF::{Count,Next,To}UTF{8,16,32}()`. SkUTF.h and SkUTF.cpp do not depend on the rest of Skia and are suitable for re-use in other modules. Some of the old UTF-{8,16} functions still live in SkUtils.h; their use will be phased out in future CLs. Also added more unit testing and cleaned up old tests. Removed functions that were unused outside of tests or used only once.

* Convert NULL and 0 to nullptr.Gravatar Ben Wagner2017-08-28
| | | | | | | | | | | | | | This was created by looking at warnings produced by clang's -Wzero-as-null-pointer-constant. This updates most issues in Skia code. However, there are places where GL and Vulkan want pointer values which are explicitly 0, external headers which use NULL directly, and possibly more uses in un-compiled sources (for other platforms).

* move sk_memset16,32,64 out-of-lineGravatar Mike Klein2017-01-24
| | | | | | | | | | | | | This helps pick it out on profiles and when debugging. This will have a negligible impact on speed in most cases (small memsets are always fast, large memsets dwarf function call overhead), and clients like Chrome that use link-time optimization should see exactly zero impact. This does however affect code size: it makes libskia 43K smaller on my laptop.

| | | | | | | | | | | | | Theory: We will accept blobs of data as utf-8 text without validation, but when it comes time to process it: count code poits or convert to code points, be careful to check for errors. TODO: SkTypeface::charsToGlyphs() needs to take a length.
