// Beating heart pattern with palettes. The heart shape is formed by a square turned 45 degees to form a "diamond" which is
// the base of the heart. Two semi-circles connect to the upper two sides of the "diamond" for the rounded heart
// portion. Depending on your resolution, you may want to play with the anti-aliasing distance to improve the 
// definition and appearance of the heart's outline.
// 
// Debra Ansell (GeekMomProjcts) 8/18/2022
// Modified by Jason Coon to include color palettes

// Ratio of the height of the heart to the length of one side of the diamond inside it
// length of one side of the diamond is also the diameter of the circle

/* DOOM Fire Eye

 Slightly modified to polar coords by Jason Coon
 Video demo here: https://twitter.com/jasoncoon_/status/1567672583436247046

 Updated 2D Fire effect, with "enhanced" dragon's breath mode. 
 Now with More, Better fire!  Version 2 has more dramatic flame,
 and an improved wind algorithm. 
 
 The method is inspired by the low-res fire in the prehistoric PSX port of DOOM!
