Enhancement: provide IndexRange for Paragraph

[ghost]

Would it be possible to provide indexRange for a given paragraph. This is the use case:

I have a paragraph with multiple styled text objects, each has its own. I need to change one style parameter, for example size.

I am using the styles.mapStyles method. then I apply styles to the whole text area at a given range.

I need a way to know where the given paragraph starts or end in reference to the text area. I tried to figure it out but I could not reach a solution.

You can already do that using these methods
getStyleSpans(int paragraph, int from, int to)
setStyleSpans(int paragraph, int from, StyleSpans styleSpans)
e.g.

int par = area.getCurrentParagraph();
int parLen = area.getParagraphs().get(par).length();
StyleSpans<S> styles = area.getStyleSpans(par, 0, parLen);
StyleSpans<S> newStyles = styles.mapStyles(...);
area.setStyleSpans(par, 0, newStyles);

I added a convenience method, so the above code can now be rewritten as

int par = area.getCurrentParagraph();
StyleSpans<S> styles = area.getStyleSpans(par);
StyleSpans<S> newStyles = styles.mapStyles(...);
area.setStyleSpans(par, 0, newStyles);

Thanks! I just downloaded it. It works fine.
