* NEW: Update error messages.

[GB.DRAW]
* NEW: The Draw class has been removed.
* NEW: Paint.Ellipse() is a new method that paints an ellipse.
* NEW: Paint.TextSize() returns the bounding box of a text like 
  Draw.TextWidth() and Draw.TextHeight() did, which is not the same thing 
  as Paint.TextExtents().
* NEW: Paint.RichTextSize() returns the bounding box of a rich text like 
  Draw.RichTextWidth() and Draw.RichTextHeight() did, which is not the same 
  thing as Paint.RichTextExtents().
* NEW: Paint.FillRect() fills a rectangle with a specific color.
* NEW: Paint.DrawImage() takes an extra 'Source' argument which is a 
  rectangle describing a piece of the source image.
* NEW: Paint.DrawPicture() now replaces the old Draw.Picture() method.
* NEW: Paint.ZoomImage() now replaces the old Draw.Zoom() method.
* NEW: The default line width after a Paint.Begin() is one pixel now.

[GB.GTK]
* NEW: DrawingArea.Painted has been deprecated.
* BUG: Don't use the 'cairo_set_device_offset' method to draw on a 
  DrawingArea, but a matrix translation.
* NEW: Support for the new Paint methods.
* NEW: The old Draw.Style methods have been moved to the Style class.
* NEW: You cannot draw on a Window anymore.

[GB.GUI.BASE]
* NEW: Do not highlight the sorted column in GridView, TreeView, ListBox... 
  if there is only one column.
* NEW: Implement a new Draw class that simulates the old one by using the
  Paint class.

[GB.JIT]
* BUG: Fix the argument order of E_NSYMBOL error message.

[GB.QT4]
* NEW: DrawingArea.Painted has been deprecated.
* NEW: Support for the new Paint methods.
* NEW: The old Draw.Style methods have been moved to the Style class.
* NEW: You cannot draw on a Window anymore.
