I am following the pset3 walkthrough and currently at the point where I have to resize horizontally.
My approach is to currently rewrite the resized bi headers as bir (eg bir.biWidth = bi.biWidth * n),
then i use multiple for loops to iterate over the row n times.
This works in resizing horizontally for n = 1, and kind of works (ie correct number of green boxes) with n = 2 but it is quite weird ( http://tinyimg.io/i/DEOgxZ9.png ) and with further values of n, the issue of the grey and white boxes above just become exarcebated.
I would appreciate any assistance to point me in the correct direction, thank you!
