Call CreateWindow function failed on WSL2

[yunnysunny]

I used canvas in WSL2 on win10.

When I call sdlcanvas.CreateWindow, it failed with error:

Error initializing SDL: No available video device

Then I switched to glfwcanvas.CreateWindow

it also emit an error:

2022/01/17 15:27:59 PlatformError: X11: The DISPLAY environment variable is missing
panic: NotInitialized: The GLFW library is not initialized

I've never used WSL2, so I don't know if I can help with this. Have you tried one of the examples from go-gl to see if they work, or if they produce the same error?

The library need GUI, but WSL has not support it now. So I think it can't render on WSL.
I have switch to the libary https://github.com/tdewolff/canvas .

You can use the library using a software backend, but that probably isn't fast since it doesn't use any hardware acceleration and isn't optimized at all. The other library is probably a good option.
