Hide Pet Unit Frame (Unit Frames, off by default) parents PetFrame to a
frame that is never shown. PetFrame_Update shows the frame again on
every pet change, so a plain Hide() would not last; with the hidden
parent the stock pet code runs unchanged and nothing draws.
XP Bar Text shows current/needed XP like the reputation bar
("1555/3000 51%"), followed by the rested bonus as before.
