You mean this function?
static void _line(int pix, int v, int h, int h2, unsigned z, unsigned z2) {
I think it cannot be directly compared, because it is not really a line
*drawing* function.
Instead, it maintains values in the Z-Buffer for a horizontal line,
comparing and storing depth values in the third dimension.
