// This version of the function performs the extraction into a user-provided mesh rather than allocating a mesh automatically.
// There are a few reasons why this might be useful to more advanced users:
//
// 1. It leaves the user in control of memory allocation and would allow them to implement e.g. a mesh pooling system.
// 2. The user-provided mesh could have a different index type (e.g. 16-bit indices) to reduce memory usage.
// 3. The user could provide a custom mesh class, e.g a thin wrapper around an openGL VBO to allow direct writing into this structure.
//
// We don't provide a default MeshType here. If the user doesn't want to provide a MeshType then it probably makes
// more sense to use the other variaent of this function where the mesh is a return value rather than a parameter.
