View / Fit Width & Fit Height

We already have a 'View / Fit all' but it would be really useful to have 2 other view options for 'Fit Width' and 'Fit Height'. Currently if you want to fit the width of the page you have to keep adjusting the zoom level and the current steps are either too bit or too small

All it would require would be 2 additional menu options under 'View'
