draw_line_distance_aa Subroutine

public subroutine draw_line_distance_aa(image_data, img_w, img_h, x0, y0, x1, y1, r, g, b, width, opacity)

Draw antialiased line using distance-based approach

Primary line drawing routine using geometric distance calculation. Provides high-quality antialiasing for lines of arbitrary width and orientation. Uses distance_point_to_line_segment for accurate alpha computation.
