Is there a way to begin a turtle path at a different point than the default
[0,0] origin?

None of the examples on https://github.com/revarbat/BOSL2/wiki/drawing.scad
have an origin of [0,0].
Example:
include <BOSL2/std.scad>
path = [[0,100], [100,100], [200,0], [100,-100], [100,0]];
rotate([-10,-10,-10])translate([-100,-10,-10])linear_extrude(0.1)stroke(path,
width=20);

When using turtle() drawing always begins at [0,0] and facing right by
default. My problem was the need to draw something that was different.
I did figure out the answer, however, by using the turtle() "state" command
to set the beginning point of the path
shape = turtle(
state = [0,1.5], // starting point
["left", // turn to use arcright next
"arcright", .125,
"move", .75,
"arcright", .125,
"move", .75,
"arcleft", .375,
"move", .625,
"right",
"untily", 0,
"right",
"untilx", 1,
"arcright", .375,
"untily", 1.25,
"arcleft", .125,
"untilx", .125,
"arcright", .125]
);

Thanks for teaching me about the state parameter to turtle(). Now that
I see your answer, it is clear that I misread your question.

Another option is to do your path starting at the origin, then use move()
to translate the entire path.
ie: path = move([10,5], p=turtle(...));
Which is pretty much how you have to do it with turtle3d()
.
