commit a330c0d3bcdd41326f37968a60e6084ad4a2e32c

Convert APIs using PointF to use Float instead
PointF is a convenient mechanism for passing around x.y values
representing 2D points. But there are downsides, including:
- Converting to PointF: You may not have the data in PointF form
to begin with, so using an API which takes PointF requires converting
the data to that form (including allocating a PointF object every time)
- Mutability: Point structures can be mutated internally, causing
unpredictability in what that mutation means. Should the library
react to those changes? Ignore them? Do defensive copies (requiring
even more allocations)? Using primitive types like Float make the
behavior more obvious (by making the data inherently immutable).
- Allocations: Whenever we use object types, there are necessarily
allocations on the Java heap for them. This puts pressure on the GC
at both allocation and collection time. Given the amount of points
being passed around (especially at morph creation time, when curves
are being split and created), this causes a lot of PointF objects to
be allocated (even temporarily). Using Float avoids that problem.
Also fixed bug with unclosed paths causing discontinuity at the
start/end point.
Bug: 276466399
Bug: 290254314
Test: integration and unit tests pass
Relnote: PointF parameters changed to Float pairs

I/zygote: Do partial code cache collection, code=29KB, data=28KB
I/zygote: After code cache collection, code=29KB, data=28KB
Increasing code cache capacity to 128KB
The reason is here as I understand:
@Composable
fun <T : Any> rememberSavedInstanceState(
vararg inputs: Any?,
saver: Saver<T, out Any> = autoSaver(),
key: String? = null,
init: () -> T
): T {
val finalKey = if (!key.isNullOrEmpty()) {
key
} else {
currentComposer.currentCompoundKeyHash.toString()
}
val registry = UiSavedStateRegistryAmbient.current
val valueProvider = remember(*inputs) { ValueProvider<T>() }
return valueProvider.updateAndReturnValue(registry, saver, finalKey, init)
}
currentComposer.currentCompoundKeyHash returns the same key for every embedded ScrollPosition
If I do not use for-loop then everithing is ok:
@Composable
fun content() {
VerticalScroller {
embeddedHorizontalScroll()
embeddedHorizontalScroll()
embeddedHorizontalScroll()
embeddedHorizontalScroll()
embeddedHorizontalScroll()
embeddedHorizontalScroll()
}
}
