PdfCraft's pdfcraft-prc crate (revision
80e26e674d1aa33078e83c8139875047f3289eb6), moved whole with its tests. It reads
PRC (ISO 14739-1), the model format of PDF 3D annotations: the container, the
bit-level primitives, the schema, tessellations and the product tree.
The code is unchanged. The package and its README are renamed, the doctests
and tests import craft_prc, and the Double code table taken from prc-rs (MIT)
has its row in ATTRIBUTION.md and its licence in licenses/prc-rs.
