// Makes a square or hexagonal grid of copies of children, with an optional masking polygon or region.
//
// Usage:
// grid2d(spacing, size, [stagger], [scale], [inside]) children;
// grid2d(n, size, [stagger], [scale], [inside]) children;
// grid2d(spacing, n, [stagger], [scale], [inside]) children;

// grid2d(spacing, [n], [stagger=], [scale=], [inside=]) children;
// grid2d(n=, inside=, [stagger], [scale]) children;
//
// Arguments:
// size = The [X,Y] size to spread the copies over.
// spacing = Distance between copies in [X,Y] or scalar distance.
// n = How many columns and rows of copies to make. Can be given as `[COLS,ROWS]`, or just as a scalar that specifies both. If staggered, count both staggered and unstaggered columns and rows. Default: 2 (3 if staggered)
// size = The [X,Y] size to spread the copies over.
// ---
// stagger = If true, make a staggered (hexagonal) grid. If false, make square grid. If `"alt"`, makes alternate staggered pattern. Default: false
// inside = If given a list of polygon points, or a region, only creates copies whose center would be inside the polygon or region. Polygon can be concave and/or self crossing.
// nonzero = If inside is set to a polygon with self-crossings then use the nonzero method for deciding if points are in the polygon. Default: false

// `$pos` is set to the relative centerpoint of each child copy, and can be used to modify each child individually.
