<p>\param enabled Whether or not to enable capturing</p>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<p>While capturing is enabled, the current window will have the
SDL_WINDOW_MOUSE_CAPTURE flag set.</p>
<p>\return 0 on success, or -1 if not supported.</p>
