using C$++$ solve

Problem $4$: The image box can be rotated and resized by dragging its upper$-$left or lower$-$right

corner. $($Unlike when dragging the other two corners, the aspect ratio will be preserved.$)$ Modify

the code in render$\_$hw$01$ so that the image is placed in the image box, even after rotation, and is

zoomed and wrapped based on zoom and wrap$\_$mode. See the second screenshot on the first page

of this assignment.

In a simple solution, and the one that is sufficient for full credit, the x and y loop limits and

increment are left unchanged. $($That is$,$ the for statements aren't changed.$)$ As before, set box$\_$wd

to the distance between points p $0$ and p$1$ and box$\_$ht to the distance between points p$0$ and p$3,$ but

note that when the image box is rotated box$\_$wd$=$p$1.$x$-$p$0.$x does not compute the correct distance

between p$0$ and p $1.$ The only other thing that needs to be done is to change how $f{b}_{2}x$ and $f{b}_{-}y$

are computed. This simple solution will skip over some pixels, the pattern of skipped pixels varies

by rotation angle. That can be seen on the screenshot on the first page. Such a solution will get

full credit. The skipped pixels can be avoided by replacing the $x,y$ loop nest with a loop nests that

iterate over frame buffer pixels of the rotated image box. That would be too tedious for a problem $4$

on a first assignment.
