+DEST_MASK specifies the mask of allowed image types.
+PIXELS and NPIXELS specify an array of pixels that are used in
+the image.  These need to be kept around for the duration of the
+image.  When the image instance is freed, XFreeColors() will
+automatically be called on all the pixels specified here; thus,
+you should have allocated the pixels yourself using XAllocColor()
+or the like.  The array passed in is used directly without
+being copied, so it should be heap data created with xmalloc().
+It will be freed using xfree() when the image instance is
+destroyed.
+If this fails, signal an error.  INSTANTIATOR is only used
+in the error message.
+#### This should be able to handle conversion into `pointer'.
+Use the same code as for `xpm'. */
