A question about r22222 (Factoring out the parsing of %V tag)

[Al Le]

Hello.

I saw the changes made in r22222 (nice number by the way! :-) And I ask 
myself why this change had to be made. IMO the parser code should be 
separated from the "pure API and data structures" code (since parsing 
might happen in another way for example, without any changes in the 
viewport API itself). But this change brings them together. What was the 
reason.

This question is for kugel (the developer who made the change) in the 
first line but for others who can explain the reason as well.

Thanks!
