wave.c: implement pipi_wave() in addition to pipi_sine(). The effect is
not yet satisfying.

wave.c: rename pipi_wave() into pipi_sine().

wave.c: change the wave arguments. The format is now eg. 150x100+10r1.3 where
150 is the wave period, 100 is the amplitude, 10 is the phase, and 1.3 is
the angle of the wave direction.
