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.
@param image_data Target image buffer (packed RGB bytes) @param img_w, img_h Image dimensions @param x0, y0, x1, y1 Line endpoints in pixel coordinates @param r, g, b Line color components [0.0, 1.0] @param width Line width in pixels (can be fractional)
