v3.4 and supporting GLFW_MOUSE_PASSTHROUGH

[J7mbo]

Hi folks! I'm displaying a transparent window overlay to highlight things on the screen (a red rectangle) and I'd really like to be able to "still click through" to things underneath this rectangle. I found that glfw itself has: GLFW_MOUSE_PASSTHROUGH from 2020 I think. I couldn't find this in the code in here, so I assume it's not implemented yet.

Would it be possible to add this without too much effort? If it's just a redirect from to a C function or something, I'd be happy to learn and follow the pattern you do for other calls, but I may need support on knowing exactly what to do.

Please let me know what you think and if you'd be willing to support this?
