Function split_stretched 

pub fn split_stretched(
    tx: &mut Transaction<'_>,
    options: &StretchOptions,
) -> Result<StretchReport>

Splits the edges under options.region that have stretched past StretchOptions::limit, until none is left or StretchOptions::max_splits runs out. See the module docs for what changes and where new vertices go. New vertices interpolate source channels, so UVs follow. The plan is computed first and committed through tx at the end: either every split lands or nothing does.

Errors

OpsError::InvalidInput for an invalid region or limit, or when the mesh holds no valid rest sizes: see capture_rest_sizes.
