In an attempt to make FLTK a smidge more modern looking, I've disabled the title bar (window decorations) on my GUI and changed box to FL_ROUND_BOX; but notice it still draws a black background outside the rounded corner.  Is there a way to change this to a transparency?  Here is an image for reference...

You should take a look at FLTK/examples/shapedwindow.cxx to see how you can create a shaped window.
