Measuring text in Skip

[dfabulich]

I'm using a LazyHStack containing Text views of various lengths, some short, some intended to wrap to multiple lines.

One of the not-well-documented features of LazyHStack is that it sets its height based on the visible items, and then proposes that height to future lazily instantiated items. So, if the first few items are just one line long, any subsequent multi-line Text will accept the LazyHStack's proposed height and truncate with an ellipsis rather than wrap to multiple lines.

As far as I know, the way to fix this is to calculate how much space I would need for multiple lines of text, and pass that in a .frame to my Text. In my experience, that means messing around with UIKit (UIFont, UIFontMetrics), to ask what the height of N lines of text would be, including line spacing (leading). It might be influenced by the user's choice of dynamic font sizes, so I can't hard code it.

I can't use UIFont/UIFontMetrics in Skip, right? What's the right way to pre-compute the height of N lines for a frame?
