Use function to control line segments

This patch only work correctly in Max version 8 or later. In Max 8 the behavior of the line object was changed significantly. The most important change is that line can now accept list messages of four or more items, describing multiple line segments, as for the line~ object. That means that you can use the function object to draw a breakpoint line segment function, and then you can use the bang message to function to send a list out of the second outlet, which will give instructions to line to draw that function with a series of messages.

This example shows how you could use a shape in the function object to control the line object to send out a timed series of MIDI control messages.
