Missing settings() reference page

[FeXd]

Was working on an old example that was using a variable to change size() of the canvas and it wasn't working. The current reference page for size() mentions:

As of Processing 3.0, to use variables as the parameters to size() function, place the size() function within the settings() function (instead of setup()). There is more information about this on the settings() reference page.

But there is no settings() reference page!

Did some quick testing and settings() appears to be working as intended. Likely content can be taken and modified from the official processing reference page here: https://processing.org/reference/settings_.html
