Fixing words being cut on page breaks

Word breaking logic will now be applied to each individual
box(word/image). This way words will no longer get cut on page breaks.

This may introduce a small issue. If the words in a single line have
different line height, there is a possiblity of some words being placed on
the next page while others stay on the previous page.
