For a depth buffer in D3D12 that is also going to be used in a texture sampler, the creation (on an Intel HD 5500 igpu) fails. e.g. SDL_GPUTextureCreateInfo type = TEXTURE_2D, format = D32_FLOAT, usage = DEPTH_STENCIL_TARGET | SAMPLER
The error messages are:
D32_FLOAT
D3D12 ERROR: ID3D12Device::CreateShaderResourceView: The Format (0x29, R32_FLOAT) is invalid when creating a View; the
Resource was already created with a fully qualified Format, which is not castable (0x28, D32_FLOAT).
D24_UNORM
D3D12 ERROR: ID3D12Device::CreateShaderResourceView: For the resource format D24_UNORM_S8_UINT, when making a D3D view, the format name for the view can't be R24_UNORM_X8_TYPELESS.
I found this is because the texture format needs to be created as _TYPELESS, then the views (depth stencil view, shader resource view) should then be created as their respective types - e.g. texture = R32_TYPELESS, dsv = D32_FLOAT, srv = R32_FLOAT
Tested and working on:
NVidia RTX 3050 (D3D12 feature set 12_2)
Intel HD 5500 (D3D12 feature set 11_1)

Under certain circumstances, processing events may try to position a child before it is fully initialized. Check the internal data before proceeding.

The window may be initially maximized or made fullscreen by the window manager for various reasons, such as automatically declaring a window that precisely fills the usable desktop space as maximized, or a "kiosk-mode" automatically making the window fullscreen.
Don't redundantly make restored or unset fullscreen calls when initially showing a window, or the expected state can be unset.

It doesn't work well with Vulkan, and Vulkan windows may not have the Vulkan flag set in all circumstances, so only enable it if we explicitly know that OpenGL is being requested instead.

The default should be the entrypoint generated by SDL_shadercross. That way it doesn't need to be hand-specified in the common workflow.

On non-compositing window managers, XIconifyWindow can trigger map/unmap events, which would toggle the window hidden/shown state. This should not be done, as a hidden window in SDL is equivalent to a withdrawn window in X, and SDL will try to set/reset state when it is shown again.
Unless the window is explicitly being withdrawn via X11_HideWindow(), set unmapped windows to the minimized/occluded state, and send a restored event when mapped again.

This hint needs to persist outside of the normal application flow, so use the environment to set the initial value, and then save the value set via SDL_SetHint() after that.

(cherry picked from commit 6bb16296b0)
External windows often handle their own events, and SDL implicitly processing events during synchronization can be unexpected and cause issues. For requests that don't change the window state beyond size or position, use the legacy synchronization method that synthesizes events from the window attributes without processing events.

this was causing problems when i was specifying non-zero buffer slots in
`SDL_BindGPUVertexBuffers`, `SDL_GPUVertexAttribute` and
`SDL_GPUVertexBufferDescription`.
`firstSlot + 1` is simply copied over from metal and d3d12 backends.
