Ok though it looks like it works because the body's font size is set to

does it use anything other than pixel font size dimensions for textural 
content.

Thanks for the RegExp but I'm not sure I want to play with replacing a 
body's HTML when I'm not 100% certain what the app's code is trying to do.

Non-textural elements are to stay unchanged.

The entire window scaling is something that the client does not want.
