corrupt waveform with large inputs*

If the input to [cos~] is greater than 1024, the waveform gets corrupt (first only half a cycle of a cosine waveform instead of a full cycle, then with higher inputs even less of the waveform). See attached patch which demonstrates the issue.

Tested with self-compiled Pd-0.45.5 on Linux (amd64).
