On Fedora, the headers for 32-bit and 64-bit are shared.
When building a 32-bit library, CMake found the header (that was installed
for the 64-bit libsamplerate development package). Because no 32-bit libsamplerate
library was installed, linking failed. (SDL_LIBSAMPLERATE_DYNAMIC was set to FALSE
because CMake could not find a library)
This lets the user to correctly detect current vsync state by reading SDL_RendererInfo.
Also fixes SetVSync's return value check (it may be positive for error too).

For SDL dynapi to work, the SDL_DYNAPI_entry symbol must be externally visible.
Adding __attribute__((visibility(default))) would not work
since version scripts override these.
This isn't the behavior on Windows, and this should probably be an application defined behavior.
If we decide we want this globally, it should probably be implemented at a higher level in SDL_OnWindowFocusLost(), and properly handle the transition of focus to a child window.
The xdg-output spec was updated to clarify its usage rules, and what was previously thought to be a bug is actually valid behavior. Gnome, when not using 'scale-monitor-framebuffer', does not scale the viewport of the display in the global compositor space, and thus the physical and logical sizes of the display will match. This value still needs to be divided by the integer scale value to get the logical output dimensions in screen units though.
Don't throttle window updates until the first swap has occurred, as the window won't actually be shown or receive the frame callback until that point and this causes new window creation to have a full 1 second delay.
Update the popup window creation documentation with additional info, remove the SDL_WINDOW_MOUSE_GRABBED flag check since it isn't a valid window creation flag and will be removed automatically elsewhere, and check for and remove the explicit skip taskbar and borderless flags since they are implicit for popup windows.
Disallow additional window operations on popups where they have no functionality or otherwise don't make sense:
- Popups cannot be set as modal to other windows (they're already child windows of a parent)
- Other windows cannot be set as modal of popups
- Popups cannot explicitly grab the mouse/keyboard (the topmost popup menu takes the keyboard focus implicitly)
- Popups cannot flash or be raised
Set the timeout max to one second from the current time or presentation time will always be greater than the timeout and the application will run unthrottled.
