Subject: [PATCH] Introduce methods for retrieving individual buffer dimensions

The new methods can be useful when one wants to get the size of the
buffer along some specific dimension, e.g. width or height.

Of course, size() could be used for this purpose, but with the new
helper methods, one has to type less.
