Comments:
----------------------------------------------
Bresenham:
You really did not need any floats or divisions
to implement Bresenham correctly. See the book
H&B for more details.
You could also implement all 8 octants with one
loop.

Cohen-Sutherland:
Your implementation of Cohen-Sutherland is way too
complicated. You are not using the outcodes correctly.
First of all, you aren't using the constants
LEFT, RIGHT, TOP, and BOTTOM that we provide to
create your outcodes (which you call flag)
Second, you are not using the calculated outcodes
to determine whether or not the line should be clipped.
For example, you are checking if (y1 > vp.top)
rather than if ((flag1 & TOP)>0)

NOTE: Make sure you turnin your code!
