*
* ///////////////////////////////////////////////////////////
* // TMP OVERVIEW OF R2 UI BEHAVIOR (WORK IN PROGRESS ...) //
* ///////////////////////////////////////////////////////////
*
*
* The ui can be in one of the following states :
*
* I CREATION MODE
* ===============
*
* No tool is displayed as "highlighted"
*
* 1) Mouse in 3D view
* --------------------
* The mouse cursor has a little star to indicate "creation mode".
* If creation is not possible at the mouse position, then there's is a little 'stop' icon shown
* No instance selection is done
*
* EVENTS :
* --------
* LCLICK -> create
* RCLICK -> cancel & restore default tool
*
* NB : we don't do creation on LDOWN or RUP in order to allow camera manipulation
*
* 2) Mouse over UI
* -----------------
* The mouse cursor still has a little star to indicate "creation mode".
* Ideally on some actions, the creation is canceled, and the default tool is backuped;
* NB nico : this is unclear to me atm, is it for button clicks only ?
* (for example just moving a slider do not seem a good reason to cancel the tool...)
* so no-op for now
* (TODO : exception for the minimap, if we want to be able to create by clicking on it ?)
*
* II CONTEXT MENU MODE
* ====================
*
* The standard mouse cursor is displayed.
*
* EVENTS :
* --------
* LDOWN / RDOWN -> cancel the menu
*
* III CAPTURED BY UI MODE
* =======================
* ... same as 'context menu mode'
*
* IV TOOL MODE
* =============
* The current tool icon is highlighted in the toolbar
*
* std tool includes :
* - Move
* - Rotate
* ...
*
* 1) Mouse in 3D view
* --------------------
* a ) Mouse over empty space in scene
* -----------------------------------
* The standard mouse cursor is displayed
*
* EVENTS :
* --------
* nothing to do here, camera event are handled by the 'UserControls' global object
* If the right button is up without being preceded by a camera move, then the context
* menu is shown
*
*
* b ) Mouse over an instance in scene that is not the selection
* -------------------------------------------------------------
* The mouse with a little circle is displayed
*
* EVENTS :
* --------
* RDOWN -> Test and see which one is best :
* - a new slection is done and the context menu is shown ?
* - nothing ? (e.g no selection and the context menu is trigerred by
* the 'UserControls' global object as usual ?
* RDOWN while maintained action : cancel the current action and restore
* state (same behaviour as most apps)
* LDOWN -> selection + tool dependent (instant action or maintained action)
* a maintained action (such as moving an entity) will usually
* capture the mouse.
* others -> tool dependent
*
* c ) Mouse over an instance in scene that the selection
* -------------------------------------------------------------
* The mouse shows the action that can be performed
* RDOWN -> same as previous
* others -> tool dependent
* RDOWN while maintained action : cancel the current action and restore
* state (same behaviour as most apps)
*
* NB : a tool may want to capture the mouse, in this case it must call CTool::captureMouse
* and CTool::releaseMouse when it is done
*
* REMARKS:
*
* - Maybe it would be cool to make camera manipulation totally orthogonal to the system,
* and transparently layered on top of it.
* This would requires using something like the middle button or some shift / control combination
* to avoid conflict with the previous events ...
*
* 2) Mouse over UI
* -----------------
* The mouse is dipslayed as usual
* Events are taken in account by the UI, not by the tool
* This is transparent for CTool derivers, because mouse events won't reach them
* Clicking in the interface doesn't change the current tool
*

*
* local road = r2.newComponent("Road")

* r2.requestInsertNode(... -> send newtork creation message for the road
