[Bf-committers] More Woody Goody

[Chris Burt]

Here is another update to the wood patch. This has an improved formula 
for creating a triangle wave. No more long-winded Fourier series, just a 
simple fabs and rint which seems to be quite effective. Made some 
changes to the code at Ton's suggestion. Still open for review! Oh and 
those screenshots are coming!
