Calculates a number between two numbers at a specific increment.
The amt parameter is the amount to interpolate between the two numbers. 0.0 is equal to the first number, 0.1 is very near the first number, 0.5 is half-way in between, and 1.0 is equal to the second number. The lerp() function is convenient for creating motion along a straight path and for drawing dotted lines.
If the value of amt is less than 0 or more than 1, lerp() will return a number outside of the original interval. For example, calling lerp(0, 10, 1.5) will return 15.
