TextBox wraps on resize

[zeyonaut]

When resizing such that the bounding box of a textbox is horizontally shortened, the text visibly wraps around and appears outside of its bounds.

crop_kids() does not actually disable this wrapping, and if the bounding box is big enough it is easily seen.

It also does not solve the fact that when TextBox is wrapping the last character in the textbox cannot be deleted.

Ahh this is a good point - I think we need to be able to distinguish between the TextBox size and the size (or size bounds) of the surface on which text is laid out.

#1209 fixes both issues that I listed, as per my testing, has the side effect of allowing for more characters than can be visibly seen. Adding a feature to horizontally scroll in the text box should probably be the next step (scroll via mouse and/or arrow keys).

Needs to be tested more for other aspects.

Edit: I'd like to see how the scrolling aspect can be added.

Edit 2: Yeah, I can't get anything to work. The scrolling system is complex and I just don't know where in the codebase I should make changes. I spent a few hours tracing events, but in vain. If someone else can take up this task, please go ahead.
