On Wayland-based platforms (i.e. very new Linux systems), setting `SDL_VIDEODRIVER=x11`

may be needed for the SDL example; the equivalent for the GLUT example is `PYOPENGL_PLATFORM=glx` (not needed on Fedora 40 Wayland).

The `skparagraph-example` example generates the below as an example of multilingual paragraph layout.

Note on Linux, it is highly sensitive to locale, and you might need to unset `LANG` and `FC_LANG` if you have unusual

(non-English) settings.

`SkSL_MinifiedSkSL.py`: (this is not a separate SkSL example, but how to generate Minified SkSL with Skia's `minifier` tool

for the same result as `SkSL_PremultipliedAlpha.py` below):
