New C++ based PLY importer and exporter
(43e9c900,
6c6edaf5,
48496f14).
About 4x-20x faster export, 8x-30x faster import compared to the
Python addon. It also fixes and improves some things:
Importing point clouds with vertex colors now works
Importing PLY files with non standard line endings
Exporting multiple objects (previous exporter didn't take the vertex
indices into account)
The importer has the option to merge vertices
The exporter supports exporting loose edges and vertices along with
UV map data
Vertex colors can be treated as either sRGB or Linear color space.
Importer supports models that use "tristrips" element instead of
"face".
