Given a particular offset in Textarea.text, I want to scroll
the Textarea instance to a vPosition where the word will be
displayed. The height, width, fontsize, fonttype for the text area
is fixed and it has only plain text associated with it.
e.g. I want to make sure that word "WORDTOSHOW" is displayed
in the visible area of textarea.
"The quick brown fox jumps over the little lazy dog.
WORDTOSHOW. This is a sample text".
I have tried several heuristics e.g. assuming fixed number of
characters in a line but they fail in several test cases.
