@GDK_CURSOR_IS_PIXMAP: type of cursors constructed with
gdk_cursor_new_from_pixmap().
@cursor_type:
@Returns:
Creates a new cursor from a given pixmap and mask. Both the pixmap and mask
must have a depth of 1 (i.e. each pixel has only 2 values - on or off).
The standard cursor size is 16 by 16 pixels. You can create a bitmap
from inline data as in the below example.
Creating a custom cursor.
/* This data is in X bitmap format, and can be created with the 'bitmap'
utility. */

@source: the pixmap specifying the cursor.
@mask: the pixmap specifying the mask, which must be the same size as @source.
@fg: the foreground color, used for the bits in the source which are 1.
The color does not have to be allocated first.
@bg: the background color, used for the bits in the source which are 0.
The color does not have to be allocated first.
@x: the horizontal offset of the 'hotspot' of the cursor.
@y: the vertical offset of the 'hotspot' of the cursor.
@Returns: a new #GdkCursor.

@Returns:
@cursor:
Destroys a cursor, freeing any resources allocated for it.
@cursor: a #GdkCursor.
