Main Changes Scilab 4.X -> 5.0
==============================
License:
========
- License changed to CeCILL (fully compatible with the GPL v2)
More information about the CeCILL http://www.cecill.info/index.en.html
Therefore, Scilab is now a 100% free software.
Graphical User Interface:
=========================
- Advanced docking system
- Follow the Tango Desktop Project http://tango.freedesktop.org/
- GUI re-written in Java Swing:
+ Same GUI for all OS (Menubars, toolbars...)
+ Window docking available using FlexDock https://flexdock.dev.java.net/
- Uicontrols are now Java objects and can be included in a graphic window with graphics
- Dialogs are now Java objects (x_message, x_dialog...)
- Completion on variable and function names avaible using TAB key or CTRL-SPACE
Graphics:
=========
- New rendering engine based on JOGL (Java Binding for the OpenGL API):
* Support 3D hardware acceleration.
* Facet ordering issues fixed with the use of Z-buffer.
- Text possibilities extended:
* Support for floating point sizes.
* Text object are able to handle matrices of strings.
- All graphic objects are fully operational both in 2D and 3D modes.
- Clipping is operational both in 2D and 3D modes.
- New functions:
* swap_handles - Permute two handles in the graphic Hierarchy.
* relocate_handle - Move handles inside the graphic hierarchy.
- Obsolete functions:
* Using xgetmouse with a flag to avoid the event queue to be cleared is now obsolete. This functionnality will be removed in Scilab 5.1.
Graphic file export:
====================
- xs2jpeg, xs2png functions added to export graphics under jpeg and png formats.
