DPX at 10 or 12 bits and Cineon (always 10) are planned as U16, so
DepthReduced, which compares sample types, never fired: a 16-bit document
saved at 10 bits lost six bits per sample silently, and a float one was
told it would be reduced to 16-bit.
FidelityWarning::BitsReduced { from, bits } names the stored depth. Float
samples always get it; U16 ones only when some sample is not already a
code value at that depth, so a frame opened from a 10- or 12-bit file
saves back without a warning. U8 widens losslessly and stays silent.
Every tests/*.rs file is its own executable that links the whole crate
graph. Move each crate's test files into tests/it/ as modules of one
tests/it/main.rs; helper modules under tests/common move with them.
These keep their own binary (own process):
- engine panic_hunt: a process-wide panic hook counts every panic.
- engine text_gamma: changes the process-wide text gamma.
- engine smart_filter_stages, mask_cache_purge: assert on global caches.
- codecs pnm_peak_memory: reads the process's peak RSS.
- photocraft mac_menu_appkit: harness = false.
