So I basically want to have a @window with rounded corners and this is what I have so far:

Code:
alias dtv.drbkg {
  var %win = @dtv.bkg | if ($window(%win)) close -@ %win
  window -Bphf +d %win 1 1 150 300
  drawrect %win 1 2 0 0 150 300
  drawrect -fd %win 14 1 0 0 150 300 10 10
  drawrect -fd %win 15 1 1 1 148 298 10 10
  drawrect -fd %win 0 1 2 2 146 296 10 10
  drawsave %win $scriptdirdtv_bkg.bmp
  close -@ %win  
}


I can't seem to get rid of the tiny corners on the rounded edge. Is there a way to do this without a .dll?
