[ ] Clarify metal-specific surface API
> right now mg_surface doesn't really give access to directly drawing in metal
we only need render encoder from the surface? -> if we just want to issue draw calls.
We'll likely need the command buffer if we want other passes? or also have get_compute_encoder().
We only need the command buffer/command queue if we want to manually create encoders, eg with different clear color
-> get pixel format / command buffer / texture
(don't get drawable as it is specific to the kind of target (window or image))
-> as helper, get simple encoders in the command buffer
maybe even _just_ get a CAMetalDrawable and pixel format, and let user code create commandQueue, buffers, encoders...
-> but we need to present the drawable to a specific commandbuffer
-> so, maybe the view should also maintain a command buffer
-> pixel format, drawable, command buffer, + helpers for encoders(passes)
--> but then, mg_surface doesn't really abstract anything (usage code needs to know which kind of surface it is to be able to draw inside it)
(well, it abstracts the creation of the context and the presentation...)
maybe we should actually abstract over that, a la sokol_gfx... And then the 2D vector graphics uses this abstract API?
-> but this is a bigger endeavour
Maybe keep surface simple, write an opengl version, then try to port painter to opengl version,
and then we will have more info to decide if we want to abstract over the different APIs.
Do surfaces for different graphics API even need to be abstracted? don't we always know which surface we're using?
->> how much do we abstract graphics API vs how much we give access to native calls...
ie we could abstract shaders, buffers, textures, pipeline, encoders, etc... but also provide access to native data structures
