Windows DPI scaling/highdpi support
Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to
change the SDL coordinate system units to be DPI-scaled points, rather
than pixels everywhere.
This means windows will be appropriately sized, even when created on
high-DPI displays with scaling.
e.g. requesting a 640x480 window from SDL, on a display with 125%
scaling in Windows display settings, will create a window with an
800x600 client area (in pixels).
Setting this to "1" implicitly requests process DPI awareness
(setting SDL_WINDOWS_DPI_AWARENESS is unnecessary),
and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.

video: Don't minimize fullscreen windows on focus loss by default when mode switching is disabled
When mode switching is disabled in a video backend, fullscreen windows are basically just fullscreen desktop windows with different internal scaling. As no mode switching occurs, there's no need to minimize them on focus loss by default. This can still be overridden by explicitly setting the internal hint for minimizing on focus loss.
This has the side effect of fixing a bug on GNOME, where, when a fullscreen Wayland window has it's focus lost and restored via alt+tab followed by switching back to windowed mode, the top portion of the window won't end up being obstructed by GNOME's top bar.

Revert "video: Prefer Wayland over X11"
This reverts commit 8ceba27d6291f1195e13608033ec439aec621fc6.
SDL Wayland support is stable, but there are a number of issues with third-party software (NVIDIA drivers, libwayland event overflow, libdecor not handling plugin load failures, Steam overlay not working with Wayland, etc.) that make it better to default to X11 at this time.
Games which would like to prefer wayland when available can use the following code before SDL_Init():
SDL_SetHint(SDL_HINT_VIDEODRIVER, "wayland,x11");

video: wayland: Use wp-viewporter for fullscreen with non-native resolutions
Wayland doesn't support mode switching, however Wayland compositors can support the wp_viewporter protocol, which allows for the mapping of arbitrarily sized buffer regions to output surfaces. Use this functionality, when available, for fullscreen output when using non-native display modes and/or when dealing with scaled desktops, which can incur significant overdraw without this extension.
This also allows for the exposure of arbitrarily sized, emulated display modes, which can be useful for legacy compatability.

If the app requested a specific renderer, even if it's not the optimal path,

video: rework how we prepare a texture framebuffer.
Now we see if we can create an SDL_Renderer, and if that renderer reports
itself as "accelerated," and added some initial heuristics to the OpenGL
renderer to make better decisions about what qualifies as "accelerated."
This adds some FIXMEs that might be merely hypothetical, and removes the
old OpenGL checks from the video subsystem that probably weren't meaningful
in modern times. This will definitely need to improve the existing list
in the GL renderer, to catch things like llvmpipe, etc.

video: Don't check if we can use a "texture framebuffer" until needed.
This prevents SDL from making an OpenGL context and maybe throwing it away
immediately by default. It will now only do it when trying to request a
window framebuffer directly, or creating an SDL_Renderer with the "software"
backend, which makes that request itself.
The way SDL decides if it should use a "texture framebuffer" needs dramatic
updating, but this solves the immediate problem.

video: Add SDL_SetWindowMouseRect.
This API and implementation comes from the Unreal Engine branch of SDL, which
originally called this "SDL_ConfineCursor".
Some minor cleanup and changes for consistency with the rest of SDL_video, but
there are two major changes:
1. The coordinate system has been changed so that `rect` is _window_ relative
and not _screen_ relative, making it easier to implement without having
global access to the display.
2. The UE version unset all rects when passing `NULL` as a parameter for
`window`, this has been removed as it was an unused feature anyhow.
Currently this is only implemented for X, but can be supported on Wayland and
Windows at minimum too.

Improve SDL_CreateWindow() fullscreen support on Windows
.. and maybe other platforms as well (though X11 was not affected)?
The issue was that passing a higher resolution than the current desktop
resolution to SDL_CreateWindow() with SDL_WINDOW_FULLSCREEN didn't switch
to that resolution (even though it did switch to lower resolutions).
When creating a fullscreen window, window->fullscreen wasn't even set
at all (only zeroed out), setting it only happened if the user explicitly
called SDL_SetWindowDisplayMode(). So without that, SDL_CreateWindow()
-> SDL_UpdateFullscreenMode() -> SDL_GetWindowDisplayMode() used the
resolution from window->windowed.w/h which were limited to the desktop size
due to some weird combination of WIN_AdjustWindowRectWithStyle() and
WIN_WindowProc() being called after a call to SetWindowPos().

Potential fix for bug 5393 - KMSDRM: using atomic mode setting breaks GPU compatibility
Substring
I was trying the KMSDRM video backend with some very simple programs that were working ok on 2.0.12. The same code won?t work on the current dev branch and I get:
DEBUG: check_modesetting: probing ?/dev/dri/card0?
DEBUG: /dev/dri/card0 connector, encoder and CRTC counts are: 4 5 6
DEBUG: check_modesetting: probing ?/dev/dri/card0?
DEBUG: /dev/dri/card0 connector, encoder and CRTC counts are: 4 5 6
DEBUG: KMSDRM_VideoInit()
DEBUG: Opening device /dev/dri/card0
DEBUG: Opened DRM FD (3)
DEBUG: no atomic modesetting support.
DEBUG: Video subsystem has not been initialized
INFO: Using SDL video driver: (null)
DEBUG: Video subsystem has not been initialized
After carefully checking, the radeon driver doesn?t support atomic modesetting. That?s not the only problem : the same happens with the amdgpu driver if we disable Display Core (kernel parameter amdgpu.dc=0, which is required to get analogue outputs working).
This is a major regression in the KMSDRM driver.
Using atomic mode setting is great, but having no fallback to the "standard KMS" is bad.

SDL_ReCreateWindow: allow to unload METAL window and switch back to OpenGL.
On older mac, where METAL Renderer METAL fails to create, it allows to switch back to OpenGL SDL_Renderer
by re-creating the window (METAL flags was previously persistent).

Fixed bug 5323 - SDL_SetWindowMaximumSize fails if Width or Height is equal to minimum Height or Width
batyastudios
Basicly there is problem and somewhat a solution: https://discourse.libsdl.org/t/setwindowmaximumsize-bug/28267
If you SDL_SetWindowMaximumSize() after SDL_SetWindowMinimumSize() with one of axes have the same value, function will have no effect.
This: (line 2144@SDL_video.c)
if (max_w <= window->min_w || max_h <= window->min_h) {
SDL_SetError("SDL_SetWindowMaximumSize(): Tried to set maximum size smaller than minimum size");
return;
}
May be changed to this:
if (max_w < window->min_w || max_h < window->min_h) {
SDL_SetError("SDL_SetWindowMaximumSize(): Tried to set maximum size smaller than minimum size");
return;
}

Merge VideoBootStrap::available into VideoBootStrap::create
The two are only ever called together, and combining them makes it possible
to eliminate redundant symbol loading and redundant attempts to connect

opengl: Allow SDL_GL_MakeCurrent() to accept a NULL window (thanks, Martin!).
This allows you to bind surfaceless contexts on a background thread to, for
example, load assets in a separate context, for platforms that have different
requirements about sharing surfaces, etc.
Martin's notes on the matter:
"Here's a patch that enables passing NULL windows to SDL_GL_MakeCurrent, if
the involved APIs allow it. Currently, this is only the case for EGL, and
even then only if some specific extensions are present (which they usually
are).
If "surfaceless" contexts are not supported, SDL_GL_MakeCurrent continues to
generate an error (albeit with a more specific error message than it used to),
so this should not break anything that wasn't broken before."
(Please see https://bugzilla.libsdl.org/show_bug.cgi?id=3695 for more
discussion.)
Fixes Bugzilla #3695.

video: NULL out pointer to freed window surface
This behavior matches SDL_RecreateWindow and makes it less likely that
another piece of code (e.g. a DestroyWindowFramebuffer implementation)
will attempt to use or free the stale surface pointer.

metal: Added some support interfaces to Apple's Metal API (thanks, Caleb!).
Caleb Cornett's comments:
"A few weeks ago, Alex added a partial Metal API to SDL2:
https://hg.libsdl.org/SDL/rev/22c8e7cd8d38
I noticed it was missing a few features that would help Metal become a
first-class citizen in SDL, so I went ahead and wrote them! Here are the new
APIs:
1. SDL_WINDOW_METAL flag for SDL_CreateWindow(). This allows the programmer
to specify that they intend to create a window for use with SDL_MetalView.
The flag is used to ensure correct usage of the API and to prevent
accidentally defaulting to OpenGL on iOS.
2. SDL_Metal_GetLayer(). This function takes a SDL_MetalView and returns a
pointer to the view's backing CAMetalLayer. This simplifies things
considerably, since in the current version of the SDL_Metal API the
programmer is required to bridge-cast a SDL_MetalView handle to an NSView or
UIView (depending on the platform) and then extract the layer from there.
SDL_Metal_GetLayer automatically handles all of that, making the operation
simple and cross-platform.
3. SDL_Metal_GetDrawableSize(). This function already exists in the current
SDL_Metal API (and is used behind-the-scenes for SDL_Vulkan_GetDrawableSize
on Apple platforms) but was not publicly exposed. My patch exposes this
function for public use. It works just like you'd expect.
Tested on macOS 10.14 and iOS 12.4."
Fixes Bugzilla #4796.

Do not overwrite window surface created by driver
If a driver's implementation of CreateWindowFramebuffer sets the window
surface, use that rather than overwriting it. A driver may set the window
surface if data cannot be passed via the CreateWindowFramebuffer output
parameters (e.g. surface palette colors).
