#Simple Mario style game
#By Chad Brubaker
#For the GREAT High School camp
#The scrolling is handled by storing a rectangle that is the part of the world we 'view'(called screen_loc)
#We move the screen_loc to keep 'player' in the center of the screen(if possible)
#and then offseting all of our drawing so that something at screen_loc.left + 30 would be at (30,y) once drawn
