REVISION SUMMARY
  this makes the "no borders" option do something: however it cause many
  other issues with many themes that weren't really designed for "no
  borders"
  it fixes the "tiny borders" for almost all themes, as the whole calculation before 
  was 
  completely wrong

TEST PLAN
  Some themes work way better now, some look broken with no border or no side borders
  some look perfect with those options
  another issue is that aurorae is going to support no borders, it has to support like 
  breeze resizing from the shadows
