Description

Running test-picture in compare mode agains the snapshots dir for piet-coregraphics gives me a lot of differences. Basically all the tests with fonts are different. Maybe most of them are differences due to the GPU, but in test 14 seems like font weight isn't working at all.

Research direction

Run test-picture in compare mode against the snapshots directory and inspect the differences for the font cases, especially test 14. Use the attached test-images.zip and the reported macOS 10.14.6 environment when comparing results. Done means the font-weight rendering issue is corrected or its platform-specific limitation is clearly established, with the relevant snapshot differences addressed.
