Conversation
A Google Chrome Developers session from 2019 states that OffscreenCanvas has better performance than <canvas> even when it's running on the main thread. Their benchmarks showed that: - OffscreenCanvas is 50% faster at creation - Text operations on OffscreenCanvas are 15--45% faster. The second benchmark is of the most value to this library. It's a bit of a micro-optimisation, but it will have benefits if a lot of text measurement is going on. <https://youtu.be/ePaUrMCL7g4?t=246> OffscreenCanvas is available in Chrome and Edge (since 2018 and 2020 respectively). Other browsers will continue to use <canvas> to measure text.
