; - add TMP2, use TMP1 for X, TMP2 for Y, position cells ??
; - set X=left pos of space allocated to object, Y=top pos??

;
; This routine itself uses R18, R19, R25 and Y. All other registers may be
; passed to the callback routine.
; However, the callback function must make sure that it doesn't modify registers
; which are to be passed to next objects later!
;
; This routine traverses the given objects skipping [R25] objects after each round
; until there is no next object.
;
; Y and R25 are preserved around the callback. Z MUST NOT be modified by the callback!
;
; @param Y object to start with
; @param r25 number of widgets to skip per round
; @param Z pointer to routine to call (using ICALL)
; @return CFLAG set if the callback returned with CFLAG set on any widget
; @return Y object on which the call returned with CFLAG set (garbage otherwise)
; @clobbers r18, r19, Y {any}
