We just pushed an early prototype of a new JavaFX Metal rendering
pipeline for macOS to a new "metal" branch of jfx-sandbox. We called it
"metal" with no bug ID or username prefix, to highlight that it is more
than an experiment: It is intended to be the branch where we will
develop the metal port. Future experimental work can be done in other
branches and those would have a username prefix.
We're not necessarily looking for contributions at this point, but if
anyone has early feedback about the approach, or wants to "kick the
tires" by building it themselves, that would be fine.
Several things are hard-coded at the moment (such as a hack to force
uploading painter since the needed glass changes haven't been done, and
a hard coded background color), and by no means does everything work yet
(e.g., no text, no decora shaders, no 3D), but basic primitive work.
