vanch3d/Calques3Dv2: Version 2.3.1

New features:

• The old Preference dialog has been split into two dialog boxes: the Customise dialog, purely dealing with the interface of the application (i.e. menus, toolbars, etc.) and the Preference dialog, dealing with Calques 3D proper (i.e. initial aspect of objects, macro-constructions, etc.). Both dialogs are multi-pages, most of them should be familiar by now.
• The split was primarily because of problems with the BCGControlBar library - which I could not solve - and because the previous layout was visually confusing. However, I'm still not convinced by the new approach, so things may change again in future releases.
• A new toolbar, Format, allows the modification of the appearance of objects (colour, shape, font) on the fly. It comes as an alternative (or replacement) for the Attribute/Structure property sheet.
• An in-place editor has been added in the MathPad View. You can now modify the comments and the mathematical expressions directly in the view (rather than using the property dialog box). Just double-click on an item and edit it. Note that, for the mathematical expressions, the contextual menu IN the in-place editor contains a sub-menu Variables that allows you to insert a reference to the value of measure objects (such as distance, length, volume, angle, etc.) that have been associated with a variable name in the view.

• The detection of previous/current version of Calques 3D for the storage and retrieval of preferences in the registry has been improved. Note that major changes (as indicated by a change in the first or second digit of the version number, i.e. from 2.2.0 to 2.3.0) will result in the registry to be cleaned up totally. This is for guaranteeing that changes in the interface (new icons, new menus, etc.) are properly reflected. A message at the first launch of Calques 3D after an upgrade will indicate the problem.
• A bug in the Macro Preference dialog has been fixed.
• SetCapture/ReleaseCapture disabled from the deformation task, solving a nasty bug (but restricting the mouse movements to the Universe/Tracing view).
• Polygons rendering have been improved. Warning: because of present incompatibility between polygons and "physical" referentials (i.e. the need for detection of intersections), polygons are only displayed when the referential is set to None or Axes. Dealing with convex polygons properly is outside of the scope of Calques 3D (wireframe geometry).
• The bug that occurred when grafting polygons have been fixed.
• The bug when trying to undo redefined objects has been fixed. Since this operation is quite complex, it cannot be undone. Consequently, all previous operations are removed from the Undo/Redo lists.
• The bug that allowed to "undo" a construction loaded from a file has been fixed. The Undo list is now initially empty.
• Contextual menus have been fixed in the MathPad, History and Graph views.
• A bug with tooltips in the Universe View, when the window is not in the front, has been fixed.
• The (disabled) Apply button in the Object Property dialog box has been totally removed.
