Merge pull request #1553 from ramox81/codex/pointcloud-attach

Point clouds: drawn from their scans, attached, cropped and stylized.

The fork's codec patch is resolved to the upstream pins: the point cloud
records landed in opencadcodec 5ef9376, carried through opencadkernel
68eeda1 and opencadgraph e204966.
