Hal Canary 118df7cf62 skottie_ios_app: Add OpenGL. 
- Consolidate Skottie logic into SkottieViewController class that no longer
    knows about which backend we use.

  - Abstract out SkiaViewController interdace which SkottieViewController
    implements.

  - Create three classes SkiaGLView, SkiaUIView, and SkiaMtkView, which all
    accept SkiaViewController objects but override GLKView, UIView, and
    MTKView.

  - SkAnimationDraw and SkTimeKeeper now SkiaViewController
    implementation details, no longer shared in headers.

Skottie iOS Example App

Metal

How to compile for the Metal backend:

cd $SKIA_ROOT_DIRECTORY

mkdir -p out/ios_arm64_mtl
cat > out/ios_arm64_mtl/args.gn <<EOM
target_os="ios"
target_cpu="arm64"
skia_use_metal=true
skia_use_expat=false
skia_enable_pdf=false
EOM

tools/git-sync-deps
bin/gn gen out/ios_arm64_mtl
ninja -C out/ios_arm64_mtl skottie_example

Then install the out/ios_arm64_mtl/skottie_example.app bundle.

CPU

How to compile for the CPU backend:

cd $SKIA_ROOT_DIRECTORY

mkdir -p out/ios_arm64_cpu
cat > out/ios_arm64_cpu/args.gn <<EOM
target_cpu="arm64"
target_os="ios"
skia_enable_gpu=false
skia_enable_pdf=false
skia_use_expat=false
EOM

tools/git-sync-deps
bin/gn gen out/ios_arm64_cpu
ninja -C out/ios_arm64_cpu skottie_example

Then install the out/ios_arm64_cpu/skottie_example.app bundle.

OpenGL

How to compile for the OpenGL backend:

cd $SKIA_ROOT_DIRECTORY

mkdir -p out/ios_arm64_gl
cat > out/ios_arm64_gl/args.gn <<EOM
target_cpu="arm64"
target_os="ios"
skia_enable_gpu=true
skia_use_metal=false
skia_enable_pdf=false
skia_use_expat=false
EOM

tools/git-sync-deps
