   line function help plz!
  ok lets say i have a region 256x256, and in this region i place two points, lemme define ''em.. L1.x = 15;L1.y = 20;L2.x = 190;L2.y = 165;  i wanna make a function that will draw a line made of points from L1 to L2. yes i could use just a line drawing function, but i need to do it made of individual points.meaning, i want to make a function that runs from L1 to L2 and places a pixel every step of the way, creating the entire line.how do i do it?  what equation would i use inside the loop to figure out what the next X,Y is each step? thx for help!
