This adds several minor changes to the gyro instruments.
* The HID Sensor Time display is now throttled to 10hz.
* Calibration for the gyro is now time based, not sample count based. Different polling rates will have drift calibrated over the same space of time.
* Pitch/Yaw/Roll readout: Yaw is prioritized, and then pitch, and then roll. This gives a more human-readable pitch/yaw/roll display, closely matching game engines.
* Pitch/Yaw/Roll text is colorized to match the axes in the 3D gizmo.
* Added set of axes to the 3D gizmo to show the "Left Hand Space" positive axis directions.
Also made accelerometer threshold for drift calibration more lenient for very noisy accelerometers.
The testcontroller tool could eventually be used to come up with a better way to profile an IMU's "stationary" noise so that this threshold can be as tight as necessary for the sake of automatic drift calibration.
(thanks @HilariousCow!)
* Added tools to Test Controller for evaluating gyroscope accuracy and IMU polling rates.
This adds a visual suite to the testcontroller tool to help validate IMU data from new gamepad drivers and HID implementations.
The 3D gizmo renders accumulated rotation using quaternion integration of gyroscope packets. If a controller is rotated 90° in real space, the gizmo should reflect a 90° change, allowing quick detection of incorrect sensitivity or misaligned axes.
Also includes:
- Euler angle readout (pitch, yaw, roll)
- Real-time drift calibration display with noise gating and progress
- Accelerometer vector overlay
- Live polling rate estimation to verify update frequency
Intended for developers working on controller firmware or SDL backend support to confirm correctness of IMU data processing.
Otherwise, the message box thread goes back to blocking, but the app's main
thread progresses to SDL_WaitThread and won't pump the event queue anymore.
On iOS, this means the messagebox won't pop back up (because it uses
SDL_RunOnMainThread, which needs the event loop to pump), but it's just bad
practice on any platform to stop pumping the event queue for indefinite
lengths of time.
So something like "index.pb" will now accept any file with a ".pb" extension,
to make macOS happy. This seems like a reasonable tradeoff.
Other minor cleanups.
Fixes#12778.
This is for internal use to signal that a mapping uses positional GameCube buttons. It's set so we know whether a mapping uses the older style labeled buttons or the newer style positional buttons. If a positional mapping is used with SDL2, then it will be ignored, since the hint is marked as defaulting true and the mapping conditional is that the hint is false.
By default, popups are automatically constrained to be completely within display bounds, so as not to cut off information and result in an unusable menu, or unreadable tooltip. In some cases, however, this is not wanted, so a property to toggle this behavior is added.
There are also cases where the client may not want a popup menu to implicitly grab the keyboard focus, as is the default behavior, so popup menus now respect the focusable flag/property, as well as being able to toggle focus grabbing via SDL_SetWindowFocusable().
The GameCube controller has a different face button layout than the Xbox or Nintendo Switch style controllers. It has the B button on the left and the X button on the right, so we should map those to SDL_GAMEPAD_BUTTON_WEST with SDL_GAMEPAD_BUTTON_LABEL_B and SDL_GAMEPAD_BUTTON_EAST with SDL_GAMEPAD_BUTTON_LABEL_X respectively.

- IsIconic/IsZoomed must be checked after sending SDL_EVENT_WINDOW_SHOWN as that may trigger window operations if any are pending from when
the window was hidden. e.g. the window may be shown, which triggers SDL_MaximizeWindow and a new WM_WINDOWPOSCHANGED where
SDL_EVENT_WINDOW_MAXIMIZED is sent, then control returns to the original WM_WINDOWPOSCHANGED which would not think the window is zoomed
and send SDL_EVENT_WINDOW_RESTORED.
* Allow custom message boxes with colors and multiple buttons to work if Asyncify is enabled
* Keep old functionality of using alert when Asyncify is not available
* Update testmessage to allow for setting random colors as the color scheme of the message box
