Module primitives 

Drawing primitives for braille graphics.

This module provides geometric drawing capabilities using industry-standard algorithms:

• Lines: Bresenham’s line algorithm (integer-only, all octants)
• Circles: Bresenham’s circle algorithm (midpoint circle, 8-way symmetry)
• Rectangles: Outline, filled, and thick border variants
• Polygons: Outline and filled from arbitrary vertex lists

All primitives operate on BrailleGrid using dot coordinates (not cell coordinates). Grid is width*2 × height*4 dots where each cell is 2×4 dots.

Examples

use dotmax::{BrailleGrid, primitives::{draw_line, draw_circle, shapes::draw_rectangle}};

let mut grid = BrailleGrid::new(80, 24)?; // 160×96 dots
draw_line(&mut grid, 0, 0, 159, 95)?; // Diagonal line
draw_circle(&mut grid, 80, 48, 30)?; // Circle at center
draw_rectangle(&mut grid, 10, 10, 50, 30)?; // Rectangle
