// Module: stroke()
// Usage:
// stroke(path, width, [endcap], [close]);
// stroke(path, width, [endcap], [closed]);
// Description:
// Draws a 2D line path with a given line thickness.
// Arguments:
// path = The 2D path to draw along.
// width = The width of the line to draw.
// endcaps = If true, draw round endcaps at the ends of the line.
// close = If true, draw an additional line from the end of the path to the start.
// closed = If true, draw an additional line from the end of the path to the start.
// Example(2D):
// path = [[0,100], [100,100], [200,0], [100,-100], [100,0]];
// stroke(path, width=10, endcaps=false);
