This should help unifying the interface and get rid of the get_info callback.
Later, I think we could create bitmaps over sections shared with some DWM process and/or host compositor.
-- v2: win32u: Create a HBITMAP backing the window surface pixels. winex11: Create a HBITMAP for the allocated surface pixels. winex11: Create XImage before initializing the window surface. win32u: Pass BITMAPINFO and a HBITMAP to window_surface_init. win32u: Move the window surface color bits to the common struct.

Does we need the 256 here?
Note that *Clr* and *PelsPer* bits in the header are not initialised, so we pick random values off the stack.

Same comments apply here. Although set_color_info particularly solves that... Although it sets the Colour(s) where there MacOS ones got removed - why is that btw?

The buffer isn't really needed but I think it makes the code more consistent, and easier to change again later [^1]. The win32u side can also safely assume it is called with enough room for any kind of bitmap info.
Note that _Clr_ and _PelsPer_ bits in the header are not initialised, so we pick random values off the stack.
Right, I'll fix the uninitialized data, thanks. I think it should not matter with BI_RGB compression, but maybe it does.
[^1]: Several drivers only use 32bit bitmap, and that could be moved out of the drivers at some point. Even for winex11 I'm not completely sure it's worth keeping the non-32bit support, but I'm trying to keep the behavior the same for now.

The macOS driver always use `biCompression = BI_RGB`, which means that the `bmiColors` field isn't used. When `biCompression = BI_BITFIELD`, the first three `bmiColors` elements provide bit masks for the R/G/B colors in the bitmap (so you can re-order them for instance).
Another semantic difference, and that's what `wineandroid` is doing, is that `biBitCount = 32` + `biCompression = BI_RGB` implies that the alpha channel is valid in the most significant bits. Otoh `biBitCount = 32` + `biCompression = BI_BITFIELDS` implies that the alpha channel should be ignored (or that there is none, for instance with a `R11B10G11` format which could be described through the `bmiColors` field, though that's only theoretical).
For the purpose of window surfaces, having an alpha channel or not has some implications on whether the surface can be used for layered windows or not. Ultimately I think we could perhaps use 32-bit surfaces with alpha channel all the time, but right now each drivers manages that a bit differently.

If it were me, I would make this a bool to indicate if we allocated it or not. Then reduce the pointer setting/scrubbing

Thank you for the extensive information.
Consistently using 32bit surfaces with alpha makes sense, although it's best to have those done incrementally ... IIRC we had some perf regressions in Mesa/i965 with similar a change.

Yeah it's a bit messy, though I hope it could be simplified in the future. I'll try to make it a bit better.
Ultimately I would like to create NT sections first, and then allocate the HBITMAP, and XSHM image from it when possible, but it looks like the only way to do that is through the XCB API, for `xcb_shm_attach_fd`, as Xlib will only let us use the old `shmget`/`shmat` API.
This would be the first case where we would need XCB in Wine, and although I see plenty of reasons to move to XCB, I'm not sure how to do introduce it properly and whether it's worth it just for that.
