when i tried it, the cursor wouldn't show unless i included a ":mask
'heuristic" property. by default, i was referring to the type of
heuristic used when you specify 'heuristic without a specific type.
if i understand correctly from kim and juri's discussion, the only
reason kim saw the cursor in his solid image without specifying a mask
was because he use an image smaller than his default character size,
so there was some empty border around the image.
i believe kim suggested something like showing a margin with the
cursor color around such images when there is no such border, which i
expect is a good for that remaining case.
