@param c The connection
@param owner_events If 1, the \a grab_window will still get the pointer events. If 0, events are not
reported to the \a grab_window.
@param grab_window Specifies the window on which the pointer should be grabbed.
@param event_mask Specifies which pointer events are reported to the client.

TODO: which values?
@param pointer_mode A bitmask of #xcb_grab_mode_t values.
@param pointer_mode \n
@param keyboard_mode A bitmask of #xcb_grab_mode_t values.
@param keyboard_mode \n
@param confine_to Specifies the window to confine the pointer in (the user will not be able to
move the pointer out of that window).
\n
The special value XCB_NONE means don't confine the pointer.
@param cursor Specifies the cursor that should be displayed or XCB_NONE to not change the
cursor.

Using the special value XCB_MOD_MASK_ANY means grab the pointer with all

This request establishes a passive grab. The pointer is actively grabbed as
described in GrabPointer, the last-pointer-grab time is set to the time at
which the button was pressed (as transmitted in the ButtonPress event), and the
ButtonPress event is reported if all of the following conditions are true:
The pointer is not grabbed and the specified button is logically pressed when
the specified modifier keys are logically down, and no other buttons or
modifier keys are logically down.
The grab-window contains the pointer.
The confine-to window (if any) is viewable.
A passive grab on the same button/key combination does not exist on any
ancestor of grab-window.
The interpretation of the remaining arguments is the same as for GrabPointer.
The active grab is terminated automatically when the logical state of the
pointer has all buttons released, independent of the logical state of modifier
keys. Note that the logical state of a device (as seen by means of the
protocol) may lag the physical state if device event processing is frozen. This
request overrides all previous passive grabs by the same client on the same
button/key combinations on the same window. A modifier of AnyModifier is
equivalent to issuing the request for all possible modifier combinations
(including the combination of no modifiers). It is not required that all
specified modifiers have currently assigned keycodes. A button of AnyButton is
equivalent to issuing the request for all possible buttons. Otherwise, it is
not required that the button specified currently be assigned to a physical
button.
An Access error is generated if some other client has already issued a
GrabButton request with the same button/key combination on the same window.
When using AnyModifier or AnyButton, the request fails completely (no grabs are
established), and an Access error is generated if there is a conflicting grab
for any combination. The request has no effect on an active grab.
This form can be used only if the request will not cause
a reply to be generated. Any returned error will be
saved for handling by xcb_request_check().
