Compile drott color demo w/o Chrome source

colr_demo_no_chrome.sh
# NOTE: prefer https://github.com/rsheeter/skia_colr/tree/colr_test, build_mac_colr.sh
git clone https://skia.googlesource.com/skia
cd skia
# download https://skia-review.googlesource.com/c/skia/+/300558
# What I actually did: click download, http, and take the Branch example, e.g:
# git fetch "https://skia.googlesource.com/skia" refs/changes/58/300558/2 && git checkout -b change-300558 FETCH_HEAD
# Probably better:
git cl patch 300558
# Now lets build it
./bin/fetch_gn
./tools/git-sync-deps
# Switch to Dominik's FT
cd third_party/externals/freetype
git remote add drott_ft_colr https://github.com/drott/freetype2-colr
git fetch drott_ft_colr
git checkout -b colr_v1 drott_ft_colr/colrV1API
# Back to root of Skia
cd ../../..
# Edit ./third_party/freetype2/include/freetype-android/ftmodule.h
# Not sure why this is necessary
# Comment out lcd renderer classes

# Download https://chromium-review.googlesource.com/c/chromium/src/+/2282815/2/skia_test/skia_test.cc
