clamp here could not always give the correct value

int16_t x = lol::clamp(int(x0), -1, 128);

The slop of the line would be wrong after clamp.

That value should not affect the slope of the line, which is always (y1 - y0) / (x1 - x0), but I see how it can offset the whole line. Thanks for pointing this out!
