msgbox 0.6.0

Simple, cross-platform message box GUI library. All it does is to show a message box modal with a OK button, which runs synchronously. All the other jobs stop until the user responds. It runs fine with OpenGL windows already open. It supports multi-platform, and maintains separate dependencies per platform, thus light-weight. - Synchronous Message Modal - Multi-platform (Linux GTK3+, Windows and OSX) - Light-weight
