Bug 411173 - added getRowHeightByPosition() to get the correct height
dependent on the visible state of the GroupByHeaderLayer
Bug 411224 - Added ColumnInsertEvent and ColumnDeleteEvent similar to
rows. Modified the ColumnReorderLayer and the ColumnHideShowLayer to
handle diffs in detail and not only in general and modified the
DynamicColumnExample to show how to do it correctly now.
Bug 411071 - Moved assembly of list changes to process out of the thread
to be calculated immediately before starting the background thread for
updating.
Bug 411497 - Added convenience constructors to hide the creation and
usage of the CompositeMatcherEditor with FilterList
Bug 411497 - updated examples for usage of the new convenience
constructors

Bug 413207: Added API for layers independent of the orientation
  - Added interface ILayerDim
  - Added Horizontal/VerticalLayerDim for old style layer implementation
  - Adapted AbstractLayer and NatTable to provide the layer dimensions
  - Added DimBasedLayer for layer implementation based on layer dimension
  - Deprecated getPreferredColumnCount/getPreferredRowCount

Incompatible API changes:
  - Added ILayer#getDim(...) = custom layer implementation which does not
    extends AbstractLayer must be adapted
Bug 413208: Updated target platform to Eclipse 3.6 (Helios)
Bug 413209: Fixed tests
  - Fixed naming
  - Reverted some change of cd58a7b5af62382e20d4a980669a09c2332f2978
  - For viewport: size <= client area size
Bug 413209: Reworked viewport layer
  - Added dim-based abstract layer for transformations
  - Implemented dim-based viewport layer
      - Cleaning up code
      - Being prepared for long data sources
      - Better scrolling behaviour e.g. for 'by page' and 'backward'
        snapping into columns/rows if possible
      - Improved handling of structural changes between minimum origin and
        origin
      - Fixing bugs, e.g. in freeze layer
  - Adapted tests to changed classes
Added more pseudo-annotations and cosmitic fixes
Bug 413209: Fixed insertion of positions at minimum position in viewport
