nui5

This is a partial feature list we would like to have for version 5 of nui:

• overall rewrite of the framework
• remove ngl and nui prefix, use a namespace instead
• better reference counting policy with adapted set of smart pointers
• multi threaded rendering
• OpenGL 2.x and GL ES 2.x engine (get rid of software and DirectX renderers)
• remove most complex widget and keep only basic and reusable ones
• remove nglString and base everything on std::string. Move nglString features to separate functions
• keep things that work well (stream, threading classes, delegates, etc).
• merge nuiMainWindow and nglWindow
• unit testing
• iOS + Android + OSX (cocoa / carbon) + Win32/64 + Linux 32/64.
• everything goes in an nui namespace
• merge / rewrite font engine
• better i18n
• bidi support
• font shaping via harfbuz
• separate the widget layout engine from the widget tree: every widget can contain other widgets. Each widget can host a set of class that will handle their inner layout.
• texture atlas
