# An image once had its own position type, for the sake of the "none" value
# (no positioning container).  That value is meaningful for any block
# element, so the shared hpos type carries it and an image is placed by the
# hpos_args option set like every other block element.

An image read from a file.  The basename names the file, which is looked
for in the image search path and converted to a format the target can use.
^:width is the image's width in the text column, ^:hpos and ^:offset place
it there, and the caption arguments caption it.
