On Windows 10 with old cpu that do not support OpenGL 3.3 (spec was released in 2010), Gupaxx will not be started.
Steps to reproduce
Launch Gupaxx on windows with cpu not supporting OpenGL 3.3
Cause
It is because the wgpu dependencies requires OpenGL 3.3 as minimum version on Windows since version v0.18.0.
Before this version, it was working because wgpu used angle for Windows.
It is a dependencies called by the eframe dependence.
Since eframe has been upgraded, (version 1.3.4 of Gupax), it is using the new wgpu version.
Getting the two versions of eframe for Windows, 0.23(which support OpenGL 3.1) and latest, using the right one at runtime if the first failed. It would solve the issue without the user to do anything at the cost of a small increase in size of the windows binary, added technical debt to the code and time developer.
EDIT: could it be possible to keep only the latest version of wgpu using angle feature ?
AND/OR
Write in README the current minimum supported version of OpenGL for each OS with link to verify easily. The user would need to upgrade his hardware or switch to Linux (wgpu on linux does support OpenGL =< 3.3).

Solutions
In theory, Gupaxx could accept cpu using at minimum OpenGL 3.1 (immediate mode is not supported before this version
