Expose native sdl functionality

[amengede]

Pygame is a wrapper around SDL, and it’s great! However advanced users would like to be able to fetch the underlying SDL functions.

Examples:

getting the address of an opengl procedure not exposed by pyopengl

Getting the raw surface from a window for vulkan rendering

A quick fix could be to expose the raw function pointer, which users could manage themselves with something like FFI.

I'd think advanced users would like to be able to use underlying SDL functionality, I don't really see what you mean about fetching.

OK I sorta get what you mean now. You mean like #3285 ?

Getting the raw surface from a window for vulkan rendering

Sure, someone could work on Vulkan support but I don't think it's priority at all. I'm skeptical people will actually use it, and it seems like it would take substantial contributor effort. It's quite strange actually that I'm unaware any of feature requests for vulkan support ever, and then you and the author of #3393 mention it on the exact same day.

To make this issue more actionable I would appreciate more specific things about what you want exposed (like SDL function names) and why.
