Here (and in similar places) the '=' should end up vertically aligned,
i.e.:

  s->b_width  = w;
  s->b_height = h;

space before '=' and after ',', same below

spaces around '+', more below

Indent the second line by one more space to make this more readable.

spaces around '&' and '>>'

I skipped the rest for now, you should get the idea.
