pub const RENDER_FACE_INDEX_MASK: u32 = 0x3ff;Expand description
Three ten-bit indices fit one hot word exactly (with the top two bits
unused), so a model whose faces are packed this way can have at most
RENDER_FACE_INDEX_MASK + 1 (1024) vertices. DEFAULT_MAX_VERTICES is
that bound, so Model::from_bytes never admits a model the packing
would mangle; a caller that passes a larger cap to
Model::from_bytes_with_vertex_cap must not pack its faces.
