ENH: Updated vtkTableExtentTranslator to support providing a different number of extents than are in the table.  Currently this may not work well when the number of pieces requested is greater than one but less than the number of pieces in the table.  Not all data will be returned in this case.

BUG: Fixed order of operations for breaking a data object away from its producer and connecting it to another pipeline.  Needed to work with executive-based pipelines.

ENH: Moved ghost level array generation in structured output from duplicated UpdateData methods in the structured data objects to a single GenerateGhostLevelArray method in vtkDataSet.  This is now possible because the extent is stored in the information object on each data object.  This code is now called by vtkSource at the end of UpdateData.  Similarly the call to Crop() was moved from vtkDataObject::UpdateData to the end of vtkSource::UpdateData.

enh: start adding new text/annotation framework. Old cache disappears, Freetype internal cache framework is used instead. Text used to be rendered using glPixmap/glBitmap in 2D, it will now be rendered in a buffer and used as a text on a quad, to allow arbitratry placement in 3D (later on, outline will be extrauded for true 3D). Also add support for orientation. Experimental for now, vtkTextActor is unchanged, vtkTextActor2D and vtkTextActor3D will be used to test new feature until transition is done.
