input_box overflow issue

[johannphilippe]

I noticed that input_box text can overflow a little bit if the elements size is limited (width overflow). It did overflow for a x limit of 30, and it doesn't for a x limit of 40 (with view_limits).

It seems to only reproduce when the input_box is inside a limit with view_limits.max.x < 40. I tried to investigate, but couldn't find the real reason for this. Actually, it is not a big deal,, since a input_box with a width < 40 is quite small (should be quite rare to use this elements with a small size like this).
