Conversion from pixel coordinates on the screen (from (0, 0) to (w, h), that is 1 pixel outside the window) to normalized coordinates (from (-1, 1) to (1, -1)) must be computed. It is basic math. Let us call xf(x) the value of the normalized coordinates, function of the x coordinate of a pixel. The value xf(x) is affine in x, meaning $xf(x) = ax + b$, $a$ and $b$ being real numbers. So
-* $xf(0) = -1 = b$, and
+* $`xf(0) = -1 = b`$, and
* $xf(w) = 1 = aw - 1$
So $xf(x) = (2x - w)/w$. Similarly, $yf(y) = (h - 2y) / h$. Let us define these two macros:
