Does Librie support font enlargement?

I read LrfFormat on the wiki for Librie,
but I have a question:

does the libre support font enlargement? 
For object is the main opponent of LRF file, if we enlarge the font in
a page, then maybe the page will extend and become two pages?
so what is the solution for this?

Thanks in advance. :)
