+ * Capture the mouse and to track input outside an SDL window.

+ * Capturing enables your app to obtain mouse events globally, instead of just
+ * within your window. Not all video targets support this function. When
+ * capturing is enabled, the current window will get all mouse events, but
+ * unlike relative mode, no change is made to the cursor and it is not
+ * restrained to your window.
+ *
+ * This function may also deny mouse input to other windows--both those in
+ * your application and others on the system--so you should use this function
+ * sparingly, and in small bursts. For example, you might want to track the
+ * mouse while the user is dragging something, until the user releases a mouse
+ * button. It is not recommended that you capture the mouse for long periods
+ * of time, such as the entire time your app is running. For that, you should
+ * probably use SDL_SetRelativeMouseMode() or SDL_SetWindowGrab(), depending
+ * on your goals.
+ *
+ * While captured, mouse events still report coordinates relative to the
+ * current (foreground) window, but those coordinates may be outside the
+ * bounds of the window (including negative values). Capturing is only allowed
+ * for the foreground window. If the window loses focus while capturing, the
+ * capture will be disabled automatically.
+ *
+ * While capturing is enabled, the current window will have the
+ * `SDL_WINDOW_MOUSE_CAPTURE` flag set.
+ *
+ * Please note that as of SDL 2.0.22, SDL will attempt to "auto capture" the
+ * mouse while the user is pressing a button; this is to try and make mouse
+ * behavior more consistent between platforms, and deal with the common case
+ * of a user dragging the mouse outside of the window. This means that if you
+ * are calling SDL_CaptureMouse() only to deal with this situation, you no
+ * longer have to (although it is safe to do so). If this causes problems for
+ * your app, you can disable auto capture by setting the
+ * `SDL_HINT_MOUSE_AUTO_CAPTURE` hint to zero.
