# Objective

There's integer overflow in `Mesh::merge` in branches like this:


405fa3e8ea/crates/bevy_mesh/src/mesh.rs (L857-L859)

we truncate `u32` to `u16` and ignore integer overflow on `u16`. This
may lead to unexpected results when the number of vertices exceeds
`u16::MAX`.

## Solution

Convert indices storage to `u32` when necessary.

## Testing

- Unit test added for `extend` function
- For changes in `Mesh`, I presume it is already tested elsewhere
