Sorry, frame_parm_table itself just lists possible frame parameters.
xfns.c, w32fns.c and nsfns.m then setup their 
[x|w32|ns]_frame_parm_handlers supplying their implementations for some 
or all of the frame parameters, used as the value of the
FRAME_RIF(frame)->frame_parm_handlers

Anyhow, it's how other several similar parameters are already handled,
the patch was little more than a copy-paste of existing frame parameters.
