Constructs a cursor by passing an array of bits (Motif and Xt only). {\it maskBits} is used only under Motif. Constructs a cursor by passing an array of bits (Motif and GTK+ only). {\it maskBits} is used only under
Motif and GTK+. The parameters {\it fg} and {\bg } are only present on GTK+, and force the
cursor to use particular background and foreground colours.
If either {\it hotSpotX} or {\it hotSpotY} is -1, the hotspot will be the centre of the cursor image (Motif only). If either {\it hotSpotX} or {\it hotSpotY} is -1, the hotspot will be the centre of the cursor image (Motif only).

The following is an example of creating a
cursor from 32x32 bitmap data ({\tt down\_bits}) and a mask
({\tt down\_mask}) where 1 is black and 0 is white for
the bits, and 1 is opaque and 0 is transparent for
the mask. It works on Windows and GTK+.
