The homework for this lesson is to modify the reticle drawing code so that you can change the position of the reticle by only changing two numbers (literal constants) in the code. Make sure you uncomment the lines that were commented, or you'll get a pretty shitty excuse for a reticle. The solution will be given in the beginning of the next tutorial.
