Description
I was following the rotating square tutorial. It works well with the versions documented in the README.md. However, when trying to upgrade:
--- a/Cargo.toml
+++ b/Cargo.toml
-piston2d-graphics = "0.44.0"
-piston2d-opengl_graphics = "0.85.0"
+piston2d-graphics = "0.45.0"
+piston2d-opengl_graphics = "0.86.0"
I am getting
thread 'main' panicked at /home/thesamet/.cargo/registry/src/index.crates.io-6f17d22bba15001f/piston2d-opengl_graphics-0.86.0/src/back_end.rs:457:9:
OpenGL function pointers must be loaded before creating the `Gl` backend!
For more info, see the following issue on GitHub:
https://github.com/PistonDevelopers/opengl_graphics/issues/103
Environment is NixOS and Wayland.

Research direction
Start with README.md and the rotating square tutorial, then reproduce it using the Cargo.toml dependency changes from 0.44.0/0.85.0 to 0.45.0/0.86.0 on the reported NixOS and Wayland setup. Trace the reported back_end.rs panic and compare behavior with the documented versions. Done means the tutorial no longer crashes with the newer versions, or the supported versions and limitation are clearly documented.
