Zooming variety

[Antonis777]

Not very important feature but it would be very handy, having a zoom scale of 75%. I think it's offering the abillity for someone to see the most part of projects while rendering not too small as 50%. (Although, thinking again that's only concerning demo users and more particularly my computer screen..!!)

Not a bad idea, will look into this after 3.6 is done.
