import im;   // for Imaging Toolkit
import cd;   // for 2D Graphics Library

This looks pretty good, looking forward to trying it out fully.
Just a quick thing, I managed to compile and run the ButtonTest
module, but when building it I had to put in various import
statements like so:

import iup.menu : IupMenu; // had to had this line
public iup.menu.IupMenu mdiMenu() { return m_menu; }

Without the added import, I get a compiler error: undefined
identifier 'menu' in package 'iup'. I had to add about 4 or 5
such imports.

I'm sure it's user error with me building it manually and not
setting up include paths properly, but anyway, just wondering if
it was planned to release this through dub as well?
