* As a test, used by: * Object buttons, tried to make it match the mockup. * Text window header. * Text window properties panel. * Panel interaction with view2d is still problematic, need to make this work properly still. * Templates are very basic, the ones there are simple but already can follow the object buttons mockup quite closely. * It's based on a three level system: panels, templates and items. To get an idea of what that means in practice, see: http://wiki.blender.org/index.php/BlenderDev/Blender2.5/UI_LayoutEngine#Panels.2C_Templates_and_Items
