Improving the foundation of our falling sand simulator

Love the gravity addition!

I notice on my machine the background is initially white and only acquires the grey background color after a sand has fallen past a given pixel. I encountered the same bug when building my own version off of this from your last post [1], my fix was to initialize the dirty set to be the full set of indexes for the first frame. [2]

  Written in C++ and using SDL, The Powder Toy is a desktop version of the classic 'falling sand' physics sandbox, it simulates air pressure and velocity as well as heat.

  

Allow me to recommend The Powder Toy[0]. It is to date, as far as I can tell, The most advanced falling sand game available, aside from maybe Noita, though the focus there is quite different from most falling sand games. It has hundreds of different elements to play with. It simulates air pressure and can with the toggle of a button simulate ambient heat, water pressure, and newtonian gravity. People have built everything from bombs to CPUs in it.

Disclaimer: I did some minor development work on TPT and am involved in the community. Still though, great game.
