The Height and Width properties were contributed as candidates to the
DDR Core Vocabulary. However, the description of these notes that they
are interpreted based on a screen being in its normal/default
orientation.

Does this mean that if I want to get the width of a display that I first
have to check if it can be rotated, and then if it can, I must check if
it is rotated, and if it is, then instead of retrieving the width, I
should retrieve the height?

As I'd probably want to do this in all cases, it means I have to be
aware of such relationships and processes just to figure out the width
of the screen so I can resize my logo banner. Surely we could also
suggest a set of convenience functions so that we can have a
CurrentWidth() and CurrentHeight() method. One could imagine that such
methods would be empowered to figure out if getting the state from the
client is possible, and if not, then to use some default, like getting
the width directly from the DDR and hoping that because this is the
default that this is the most likely correct answer.

There's nothing in the charter about the DDWG suggesting convenience
functions. But they'd be nice to have anyway.
