It's legitimate to have a surface with 0 width or height (null 'pixels' pointer).
But calling SDL_FillRects would wrongly set the error "You must lock the surface".

multiply gyro values by sensitivity
When the hardware calibration fails, values read from sensors need to be multiplied by default sensitivity (16 for gyro, 1 for accelerometer).

When watching for hotplug events we can poll the inotify fd, but we
still need to scan /dev/input once per process, otherwise we'll fail
to detect devices that were already connected.
Flatpak[1] and pressure-vessel[2] are known to use user namespaces,
therefore udev event notification via netlink won't work reliably.
Both frameworks provide a filesystem API that libraries can use to
detect them. Do that, and automatically fall back from udev-based
device discovery to the inotify-based fallback introduced in Bug #5337.

Evdev headers aren't actually included in the base system (well, it has a private copy), they are available through the devel/evdev-proto port instead. We also have devel/libinotify and devel/libudev-devd shims, I didn't verify whether they work with SDL.

As it is, SDL2's built-in config on macOS for Metal excludes Apple Silicon. This is due to thinking that the 64-bit Mac platform would always be x86_64. My patch fixes this by using the catch-all of 64-bit platforms.
This fixes bad report parsing for various newer Xbox controllers, and this driver is now preferred over XInput, since it handles more than 4 controllers.

This patch adds support to the GameController framework on macOS Big Sur and later, adding support for MFi controllers as well as rumble support for PS4 and Xbox One. There is some code to make sure that the IOKit joystick handler doesn't include two controllers at once.
While the GameController framework is present in earlier versions of macOS, there was no public, approved way of checking if a specific IOHIDDevice is a controller that GameController could handle. This was changed in Big Sur.
