Simple graphical data types

<!-- ##### SECTION Long_Description ##### -->
<para>
GDK provides the #GdkPoint and #GdkRectangle data types for representing pixels
and sets of pixels on the screen. Together with Cairo's #cairo_region_t data
type, they make up the central types for representing graphical data.
</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>
#cairo_region_t is usually used for managing clipping of graphical operations.

<!-- ##### STRUCT GdkPoint ##### -->
<para>
Defines the x and y coordinates of a point.
</para>

@x: the x coordinate of the point.
@y: the y coordinate of the point.

<!-- ##### TYPEDEF GdkRectangle ##### -->
<para>
Defines the position and size of a rectangle. It is identical to 
#cairo_rectangle_int_t.
