The crate denies panics, but asserts and slice indexing were reachable
from arguments: pixel strides, buffers that are not whole pixels or a
destination shorter than the source, single-colour slices shorter than
the channel count, CLUT and pipeline dimensions, and LUT sizes.
Every such check now returns CmsError::InvalidArgument. Buffer
conversions validate once per call, before any pixel is written, so the
per-pixel loops carry no extra checks; internal callers that already
guarantee lengths use crate-private unchecked evaluation.
Pipeline, Clut and Lut3d keep their fields private (read through
accessors) so a validated value cannot be changed into one that panics.
Pipeline::new checks matrix shapes and channel counts; Clut::new and
Clut::sample check grid, outputs and the table size limit.
API changes (unreleased crate):
- Transform::eval, eval_fast, convert_u8/u16/f32, apply,
convert_bytes_many and from_pipeline return Result.
- Pipeline::new, extend and eval, Clut::new, sample, eval,
eval_trilinear and eval_multilinear return Result.
- GamutCheck::delta_e and out_of_gamut, Lut3d::from_transform,
LutFile::identity and from_fn, synth::cmyk_profile and coated_cmyk
return Result.
- Pipeline, Clut and Lut3d fields are read through methods.
