This part of the patch changes the definitons of the member variables
from 'C arrays of extent 2' to QHVContainer and fixes the code where
ints were used to index into the array.
To not drown in renames, keep the locally-defined enum 'Orientation',
and create a local version of QHVContainer whose index operator is
overloaded for both Qt::Orientation and the local 'Orientation'.
Follow-up patches will remove these, then, completely.
After this patch, NOrientations is no longer used, and consequently
removed.
