Game crash on RenPy 7 Web due to video errors about renpy

My bad, I didn't see your Windows tests were done in a VM. That's indeed expected.

I've pushed a PR in renpyweb to fix the crash on the other (non-VM) platforms.

The crash comes from the fact that emscripten.webgl_enable_extension() is not defined for Ren'Py 7. Either we define it the same way as in renpy-build#f875ff4 or just prevent the call for python 2.

It is strange that using gles2 fails on your Windows box though, as even the oldest WebGL version supports it. There might be something to fix here, but I'm not OpenGL savvy enough to figure out what.

It's probably not that strange... as I said, my Windows runs on a QEMU VM without any GPU, either real or simulated by the hypervisor. Most GPU-accelerated software I need runs fine however, since I installed proper software-accelerated drivers for OpenGL, but they probably don't support the latest and greatest APIs at a system level, despite the browser technically having support... and maybe that's what tripping RenPy on there and making it fall back. (DirectX software rendering is instead provided by Microsoft and actually hardware-accelerated via RDP using the client's GPU, iirc)

@Kassy2048 Finds the underlying issue. We'll fix that, but in general we don't support Ren'Py under emulation/virtualization/etc, unless it's platform provided.
