◆ M_1_SQRTPI

We want to know how much of a pixel is covered by a line. Here, we imagine the square pixel is a circle with the same area and try to find the intersection area. The overlap area is a circular segment. https://en.wikipedia.org/wiki/Circular_segment The formula for the area uses inverse trig function and is quite complex. Instead, we approximate it by using the smoothstep function and a 1.05f factor to the disc radius.
