Retrieve position of crosshair cursor
(x, y) = ds9_get_crosshair()
(x, y) = ds9_get_crosshair( [ coord_sys, handle ] )
Return the position of the crosshair cursor, under the same coordinate system and return-value constraints as those described for ds9_get_coords. (0,0) will be returned when the current frame is not displaying an image. (-1,-1) will be returned upon error (e.g. when no frames exist).
When an image is loaded into a frame the crosshair cursor will be positioned at its center, even if the crosshair is invisible.
