ximtool binary package in Ubuntu Jammy amd64

 Ximtool provides an image display capability to remote client
 applications for IRAF using the standard imtool/iis image display
 protocol. The image display server allows a number of image frame
 buffers to be created and displayed. The client can read and write
 data in these frame buffers. Any frame or combination of frames can
 be displayed. Various display options are provided, e.g., zoom and
 pan, flip about either axis, frame blink, windowing of the display,
 and colortable enhancement.
