## mask

Arguments: pixmap-or-cursor

Returns the mask of pixmap-or-cursor. The mask is a bitmap that defines the transparent area of the pixmap or mouse cursor. The mask value should be a 1-bit-per-pixel texture with a 1 wherever the pixmap or mouse cursor should be transparent (destination is left alone) and a 0 wherever the pixmap or mouse cursor should be opaque (the pixel for that location is drawn). The mask of a pixmap (if any) is usually specified either by setting the mask-contents property or by calling generate-mask.

mask is a property of the `cursor` and `pixmap` classes.
