++Using Skia instead of Rsvg for rendering OT-SVG
++===============================================
++
++Follow instructions at:
++    https://github.com/HinTak/skia-building-fun/
++to build Skia m116.
++
++You should get a "skia-m116-bin.zip" at the end.
++
++skia-python bundles m87; m98 introduces COLRv1, and m103 introduces
++OT-SVG. For this purpose, m103+ is the minimum.
++
++
++PREPARATION:
++
++    mkdir skia/
++    pushd skia/
++         unzip "<downloaded>"/skia-m116-bin.zip
++    popd
++
++BUILDING:
++
++Run:
++   CC=clang++ ./configure
++
++in freetype2. Using a C++ compiler is necessary (Skia is heavy-duty
++c++ code). Use the same c++ compiler for both skia and ft2-demo.
++In the case of https://github.com/HinTak/skia-building-fun/, clang++.
++Mix-and-match results in segfaults at runtime.
++
++Then just build as normal.
++
++There is a "-s <N>" switch for both ftview and ftgrid to use skia
++at launch time, instead of rsvg. It is not possible to dynamically
++re-render without restart. Limited by current design.
