Are built-in examples on GitHub too? I'd like to propose an improvement to the Fade sketch

[YakovL]

Hello Arduino Dev community, I've searched this repo but haven't found, so please guide me where the built-in examples of Arduino IDE are stored and can I propose some improvements?

More specificly, the Fade sketch has these lines:

if (brightness == 0 || brightness == 255) {
  fadeAmount = -fadeAmount ;
}

which I'd say is not a good code as if we change fadeAmount to, say, 7 than we will miss the == 255 value (brightness will rise up to 7*36 = 252 and then will become 259 and will grow further). It should be

if (brightness <= 0 || brightness >= 255) {
  fadeAmount = -fadeAmount ;
}

instead, I would say. So, where do I propose such improvements?

I noticed the pullrequest, so seems this one is answered. Closing.
