Does `LazyColumn` measure the entire list on first composition, and only composes the visible items? Or is the measurement also only done for the visible items?

My list seems to be taking a long time (several seconds) to measure, and I can't seem to optimize it any further.

Last time I looked it only subcomposes the visible items, which means it can only measure them as well. 

What does the Android studio profiler say is taking all the time?

Looking at the profiler, I was able to optimize a bit.
A lot of time was taken up by `rememberVectorPainter()` calls from an icon which was repeated many times. Replaced with one call for the whole list which helped a lot. Text layout also seems pretty heavy, I tried setting `softWrap` to false, which also helped a bit. Still slower than I'd like.

Investigating further...
