struct MRILIB::MriSlice

Single 2D MRI slice (pixels + slice→RAS transform) used as the volume's storage unit.

Mirrors the on-disk FIFFB_MRI_SLICE record so that round-tripping through COR.fif is lossless: each slice owns its pixel buffer in the source's native FIFFV_MRI_PIXEL_BYTE / _WORD / _FLOAT encoding, its width/height in pixels and millimetres, and an explicit FiffCoordTrans mapping slice (column, row) to MRI surface RAS. The slicing pipeline and the COR.fif writer consume slices directly every format-specific loader (MGH, NIfTI, raw COR) builds its volume as a vector of these.

Ported from mriSliceRec in the original MNE C mne_make_cor_set.
