cineon_log_to_lin takes the exponent scale from its caller. Interpret
Footage > Cineon Settings passes 1 (Gamma 1 gives linear light) and the
Cineon Converter passes 1.7, as before, so the converter's output and
its default Gamma 1.7 are unchanged. The converter's Linear to Log, Log
to Log reference and GPU shader return to their earlier code.
A test checks the converter at its default Gamma and at 2.4, for all
three conversion types, against the earlier formula.
effectcraft_project::cineon_log_to_lin does the log-to-linear conversion
for Interpret Footage > Cineon Settings and the Cineon Converter's Log to
Linear. Both raise the result to 1 / Gamma, so Gamma 1 gives linear light
and the same Gamma gives the same values in both. The converter's Linear
to Log, its Log to Log reference and the GPU shader use the same Gamma
scale, with a smallest Gamma of 0.01 / 1.7 (CINEON_MIN_GAMMA).
A test runs the converter at Gamma 1.7 (the default), 1 and 2.4 and
checks it against Cineon Settings at each code value.
Cause: Apply Color LUT's only parameter, `lut`, was ParamUi::Hidden (set only
through commands), so the effect could not be used from the UI. Effect
Controls also had no widget for any ParamUi::Text parameter (only EXtractoR's
channels had one), so Cryptomatte's Selection, the OCIO effects' config file /
file / config names and Colorama's Output Cycle could not be set either.
Fix: a new ParamUi::File { filters } for paths. Effect Controls shows the
file's name (None when empty) and a Choose... button that opens the host's
file dialog with those extensions and sets the path (prop.set, so agents use
the same command). As in After Effects, applying an effect with an empty file
parameter from the UI (Effect menu, Last Effect, drops, Effects & Presets)
opens the file dialog straight away; cancelling keeps the effect without a
file. Apply Color LUT's LUT (.cube) and the OCIO Config File (.ocio) and File
(.cube/.3dl/.csp/.cc/.ccc/.cdl/.spi1d/.spi3d/.spimtx) use it. Text
parameters get a single-line field that sets the value when it loses the
focus (Esc keeps the old text). Saved projects are upgraded on open: a
Hidden or Text parameter whose spec is now a File parameter takes the File
UI and keeps its path (effects::migrate). docs/effects.md regenerated.
This covers #473's first part (the Selection field); picking mattes in the
viewer, the layer popup from the file's metadata, the GPU path and quoted
commas are separate.
Tests: effects hidden_and_text_paths_become_file_parameters (migration); ui
file_and_text_parameters_have_widgets (the LUT is asked for on apply and
inverts red to cyan, the Choose... button picks another LUT, typing into
Cryptomatte's Selection sets it).

(cherry picked from commit 403863f703999d19d3a83d9976f76bdc7577e682)
Apply Color LUT, OCIO CDL / Color Space / Display / File / Look Transform and
Color Profile Converter compile to colour programs (effects::color_program,
built next to the CPU effects) that fx_lut.wgsl interprets per pixel; LUTs
(1D, 3D, cineSpace shapers, inverses) are read from the storage buffer with the
CPU's nearest / trilinear / tetrahedral interpolation. Lumetri's Input LUT and
Look no longer force the CPU. Custom .ocio configs stay on the CPU.

transfer functions and Bradford adaptation; CDL v1.2 maths; .cube/.3dl/.csp
and .cc/.ccc/.cdl file transforms with nearest/trilinear/tetrahedral
interpolation and inverse; displays/views/looks.
