BUG: An update progress was send every time a cell center was computed, which could really slow down the process if that actually updates a GUI.  Now only send an update every 1000th cell center computation.

BUG: 5445: tweaks on 1.2.3 upgrade: the minimal set of warnings for bcc was determined and is now in place, MS Visual Studio warning suppression removed to see which are actually still needed in 1.2.3

ENH: Methods to initialize a contour widget from user defined geometry. Also set the interaction state appropriately.

BUG: 5445: tweaks on 1.2.3 upgrade: cosmetic changes to keep itk and vtk zlibs as close as possible, suppress more compiler warnings, updated readme, added HAVE_UNISTD_H test, removed some warning suppression to see if the new zlib fixed them

BUG: fixing uninitialized memory access; set numTypes to the number of entries in the type array; add VTK_STRING to the type array

ENH: Modified code to set ContentType in IDs selection case for emplty selection, so that extract selection filter will pass the content type checking.

BUG: make the string static, otherwise the contents are gone when we exit the functions

ENH: This is the single-source-file version of SQLite 3.4.1.  Before we add these to the build there are several hundred compile-time warnings that will be fixed.  I'm adding the files before we fix them so we can have CVS track the changes and generate diffs to submit back to the SQLite maintainers.
