			==== applyFunc ====
			----

			Calls the provided function ''f'' on every component, and sets this vector's components to the return values of the function.

			The function receives the following values as arguments: first, the value as a {{type\|number}}, then the index ({{type\|integer}}, 1 is x, 2 is y, etc.) The function is expected to return a {{type\|number}}.
