With David Gobbi's help, I have fixed most of the compiler errors when building VTK as C++11, but a few remain, which currently appear as warnings here:

<http://open.cdash.org/viewBuildError.php?type=1&buildid=2139702>

They could be fixed by blindly casting, but a better solution may be to change some of these floats to doubles.  I'm not sure if these are deliberately float, or left over and never changed from the big float->double changes long ago.  Currently, there's a bunch of double->float->double conversions.  Changing said floats to doubles would require changing public API.

The classes in question are: vtkCellTreeLocator, vtkKdTree, vtkContext2D, AreaLayout and AreaRepresentation classes.

Could someone in the know take a looksie, or shall I just cast everything?

Cheers,
