Would like to see an Fl_Window control for window transparency (on platforms that support it). This is actually very functional for paint programs that need to be semi-transparent to allow one to visually compare image content with that of another application. Also useful for a paint app to allow tracing the content of another window. (What I need it for). OSX (I've verified this technique works well with 1.3 svn current): https://stackoverflow.com/questions/26686382/how-can-i-make-a-window-transparent-in-windows-mac-os-x-and-linux-using-fltk Windows (have not tested): https://www.gidforums.com/t-7375.html https://www.gidforums.com/t-14481.html
