Arguments: pixmap x y value
Sets the value of the specified pixel of the mask texture of a pixmap
by calling contents-set on the mask texture,
and returns the new value. Does nothing and returns nil if the pixmap has no mask texture. See contents-set
for more information.
Note that mask-contents-ref is setf'able and it is recommended you use setf and mask-contents-ref rather than this function.
