Using an unscaled buffer just results in the compositor scaling up the low-res cursor image for output, resulting in it appearing blurry. Always use the scaled cursor to ensure that it appears sharp and matches the native system look.
If you're building in a C99 or newer environment, we'll automatically include stdbool.h.
If you're building in a C89 or C90 environment, we'll assume that stdbool.h isn't available and define bool as an unsigned char. If you have a working stdbool.h and want SDL to use it, you can either include stdbool.h before SDL headers, or define SDL_INCLUDE_STDBOOL_H in your project.

If the cursor shape protocol is supported, the compositor will handle cursor themes and sizes automatically, so querying the properties with DBus serves no purpose as the values are never used.
We should wait for the state to stabilize before SDL_ShouldQuit() returns.
For example:
Thread A initializes and increments a use refcount
Thread B skips initializing and increments the use refcount
Thread B starts cleaning up and checks the use refcount
Thread A starts cleaning up, returns because SDL_ShouldQuit() returns false (not initialized), not touching the use refcount
Thread B returns because the use refcount isn't zero
Now we have the state where the refcount is greater than one and both thread A and B have attempted to cleanup.
With this change:
Thread A initializes and increments a use refcount
Thread B skips initializing and increments the use refcount
Thread B starts cleaning up and decrements and checks the use refcount
Thread A starts cleaning up, waits for thread B
Thread B returns because the use refcount isn't zero
Thread A continues and decrements and checks the use refcount, and finishes cleaning up because it has reached 0.
Note that SDL_FlushIO() doesn't make promises about file data sync but that
is intended to be changed in the IOStream code in a later commit.
Fixes#10886.
