skia: A C++ repository from coderedart

Skia is a complete 2D graphic library for drawing Text, Geometries, and Images.

See full details, and build instructions, at https://skia.org.

This fork is basically the latest skia milestone + SkiaSharp's "C" bindings. The primary usecase is ckia_sys crate, but because skia's git repo is huge (hundreds of MB), i decided to keep the crate separate from the skia source.

To upgrade to a new milestone, just do the follow:

copy the following directories and install_files
ckia directory which contains skiasharp's stable ABI headers/sources.
this README.md file
.gitub/workspaces which checks if our changes build properly for different targets.
Add the following to third_party/icu/SkLoadIcu.h and third_party/icu/SkLoadIcu.cpp
SkLoadIcu.h: 1. bool SkLoadICUMemory(void*); inside win32 def 2. static inline bool SkLoadICUMemory(void*) { return true; } outside win32 def
SkLoadIcu.cpp: bool SkLoadICUMemory(void* icudtl) { return init_icu(icudtl); }
add the following to BUILD.gn.
