Make the definition of the brace height and draw length adjustable

[stfnp]

Brace height and draw length are measured against the coordinate origin (red). The position of the origin relative to the bow limb is determined by the handle geometry, i.e. length, setback and angle. Currently with the profile curve as the reference, which lies at the back of the bow.

Instead, define the handle length and setback relative to the edge of the limb as shown below. This way, the brace height and draw length are measured w.r.t. the belly side of the bow/grip by default, i.e. when handle length and setback are zero. This is the more usual convention as opposed to measuring against the back.

Even when handle length and setback are not zero, i.e. when the bow has a riser, this definition makes more sense because the reference point is actually a geometrical point on the riser, where the limb attaches.

Please make possible to use AMO standard definition of the draw lenght. So 26,25" from the pivot point + 1,75" = 28" draw length. http://www.outlab.it/doc/amostd.pdf
