Main Gtk struct.
A cairo_surface_t represents an image, either as the destination
of a drawing operation or as source when drawing onto another
surface. To draw to a cairo_surface_t, create a cairo context
with the surface as the target, using cairo_create().
There are different subtypes of cairo_surface_t for
different drawing backends; for example, cairo_image_surface_create()
creates a bitmap image in memory.
The type of a surface can be queried with cairo_surface_get_type().
The initial contents of a surface after creation depend upon the manner
of its creation. If cairo creates the surface and backing storage for
the user, it will be initially cleared; for example,
cairo_image_surface_create() and cairo_surface_create_similar().
Alternatively, if the user passes in a reference to some backing storage
and asks cairo to wrap that in a cairo_surface_t, then the contents are
not modified; for example, cairo_image_surface_create_for_data() and
cairo_xlib_surface_create().
Memory management of cairo_surface_t is done with
cairo_surface_reference() and cairo_surface_destroy().
