This is a (very) hidden method added by the compiler when it processes
Form files. As you can see, it is automatically called first thing in the
constructor and is responsible for creating and initialising all the
controls inside the form and setting the form's properties. It basically
applies all the things you did in the IDE's graphical form editor.

I doubt it is documented anywhere, but the function name is hardcoded into
the compiler. I also don't know off the top of my head if there are other
hidden functions like this. In any case, you should be fine if you follow
a sensible naming scheme :^)
