When using Icon.kt, I personally would expect that passing Color.Unspecified as the tint would result in no tint being applied to the icon at all (in other words, a null color filter would be passed to the Painter and the colors that are rendered would just be whatever the VectorAsset or ImageAsset internally draws).

This is currently not the case, as passing Color.Unspecified results in a transparent color filter being applied (meaning the icon is not rendered at all).

This behavior is particularly important to support multi-colored icons, where you need to avoid a tint being applied all together.

// EXPECTED BEHAVIOR: no tint is applied to the vector asset
// ACTUAL BEHAVIOR: a transparent tint is applied to the vector asset
Icon(
    asset = someVectorAsset,
    tint = Color.Unspecified,
)
