<para>
GDK provides the #GdkPoint, #GdkRectangle and #GdkRegion data types for
representing pixels and sets of pixels on the screen.
</para>
<para>
#GdkPoint is a simple structure containing an x and y coordinate of a point.
</para>
<para>
#GdkRectangle is a structure holding the position and size of a rectangle.
The intersection of two rectangles can be computed with
gdk_rectangle_intersect(). To find the union of two rectangles use
gdk_rectangle_union().
</para>
<para>
#GdkRegion is an opaque data type holding a set of arbitrary pixels, and is
usually used for clipping graphical operations (see gdk_gc_set_clip_region()).

<!-- ##### STRUCT GdkDeviceInfo ##### -->
<para>
The #GdkDeviceInfo structure contains information about a 
device. It has the following fields:
</para>

@deviceid: a unique integer ID for this device.
@name: the human-readable name for the device.
@source: the type of device.
@mode: a value indicating whether the device is enabled and
       how the device coordinates map to the screen.
@has_cursor: if %TRUE, a cursor will be displayed indicating 
             the current on-screen location to the user. Otherwise,
             the application is responsible for drawing a cursor 
             itself.
@num_axes: the number of axes for this device.
@axes: a pointer to an array of GdkAxisUse values which
       give the mapping of axes onto the possible valuators
       for a GDK device.
@num_keys: the number of macro buttons.
@keys: a pointer to an array of #GdkDeviceKey structures  
       which describe what key press events are generated
       for each macro button.

<!-- ##### FUNCTION gdk_input_list_devices ##### -->
<para>
Lists all available input devices, along with their
configuration information.

@Returns: A #GList of #GdkDeviceInfo structures. This list
          is internal data of GTK+ and should not be modified 
          or freed.

<!-- ##### FUNCTION gdk_input_motion_events ##### -->

</para>

@deviceid: the device to configure.
@index: the index of the macro button.
@keyval: the key value for the #GdkKeypressEvent to generate.
         (a value of 0 means no event will be generated.)
@modifiers: the modifier field for the generated 
            #GdkKeyPressEvent.
