Detailed Description

The primary purpose of this API is to avoid unnecessary mesh conversion for the final output of a modified mesh.

This API handles the case when the modifier stack outputs a mesh which does not have Mesh data (MPoly, MLoop, MEdge, MVert). Currently this is used so the resulting mesh can have BMEditMesh data, postponing the converting until it's needed or avoiding conversion entirely which can be an expensive operation. Once converted, the meshes type changes to ME_WRAPPER_TYPE_MDATA, although the edit mesh is not cleared.

This API exposes functions that abstract over the different kinds of internal data, as well as supporting converting the mesh into regular mesh.
