+
+  The Sieve of Eratosthenes -- a simple shader by ProfJski
+  An early prime number sieve: https://en.wikipedia.org/wiki/Sieve_of_Eratosthenes
+
+  The screen is divided into a square grid of boxes, each representing an integer value.
+  Each integer is tested to see if it is a prime number.  Primes are colored white.
+  Non-primes are colored with a color that indicates the smallest factor which evenly divdes our integer.
+
+  You can change the scale variable to make a larger or smaller grid.
+  Total number of integers displayed = scale squared, so scale = 100 tests the first 10,000 integers.
+
+  WARNING: If you make scale too large, your GPU may bog down!

+
+      If the magnitude of the number becomes greater than 2, then from that point onward
+      the number will get bigger and bigger, and will never get smaller (tends towards infinity).
+      2^2 = 4, 4^2 = 8 and so on.
+      So at 2 we stop iterating.
+
+      If the number is below 2, we keep iterating.
+      But when do we stop iterating if the number is always below 2 (it converges)?
+      That is what MAX_ITERATIONS is for.
+      Then we can divide the iterations by the MAX_ITERATIONS value to get a normalized value that we can
+      then map to a color.
+
+      We use dot product (z.x * z.x + z.y * z.y) to determine the magnitude (length) squared.
+      And once the magnitude squared is > 4, then magnitude > 2 is also true (saves computational power).

+
+  The screen is divided into a square grid of boxes, each representing an integer value.
+  Each integer is tested to see if it is a prime number.  Primes are colored white.
+  Non-primes are colored with a color that indicates the smallest factor which evenly divdes our integer.
+
+  You can change the scale variable to make a larger or smaller grid.
+  Total number of integers displayed = scale squared, so scale = 100 tests the first 10,000 integers.

+
+      If the magnitude of the number becomes greater than 2, then from that point onward
+      the number will get bigger and bigger, and will never get smaller (tends towards infinity).
+      2^2 = 4, 4^2 = 8 and so on.
+      So at 2 we stop iterating.
+
+      If the number is below 2, we keep iterating.
+      But when do we stop iterating if the number is always below 2 (it converges)?
+      That is what MAX_ITERATIONS is for.
+      Then we can divide the iterations by the MAX_ITERATIONS value to get a normalized value that we can
+      then map to a color.
+
+      We use dot product (z.x * z.x + z.y * z.y) to determine the magnitude (length) squared.
+      And once the magnitude squared is > 4, then magnitude > 2 is also true (saves computational power).
