getDi?mension() should return DimensionType

[mateusz@…]

I'd suggest to provide better type safety in getDimension() functions.
Now, it returns unsigned int or int type.
But in fact, it returns values equvalent to enumerators from Dimension::DimensionType enum.

So, why not to return Dimension::DimensionType itself instead of int?

Example:

Dimension::DimensionType getDimension()
{
   return Dimension::P
}

Digression:

Java was a condemned language related to this feature until latest Java 5.0.
Just now Java 5.0 provides type safety related to enums. In previous version there were no real enums.
So, I'd suggest to not to continue this condemnation in C++.
