## mask-handle

Arguments: pixmap

Returns the handle to the device-dependent bitmap for the mask texture of the argument pixmap, if it has been given one by calling open-pixmap-handle, and otherwise returns `nil`. This function is useful for determining whether the pixmap currently has such a handle, though the particular handle is not useful for Common Graphics code. This handle corresponds to the mask texture stored in the mask property of the pixmap; see pixmap-handle for the handle corresponding to the main texture.
