Specifies which render front-end to use. This option used to have more scope in earlier versions of wezterm, but today it allows two possible values:
OpenGL- use GPU accelerated rasterization (this is the default)
Software- use CPU-based rasterization.
WebGpu- use GPU accelerated rasterization (Since: Version 20221119-145034-49b9839f)

WezTerm will automatically select

The feature described in this section requires version 20221119-145034-49b9839f of wezterm, or a more recent version.
The WebGpu front end allows wezterm to use GPU acceleration provided by a number of platform-specific backends:
- Metal (on macOS)
