* Upgrade Vello to a git main revision that honors the brush's interpolation alpha space
* Interpolate Vello gradients with straight alpha, matching the SVG renderer
* Draw the gradient picker strip and fill swatches as SVG so transparency previews with straight alpha
* Keep gradient stop handles opaque so a transparent stop's RGB stays visible
* Paint a stopless gradient's picker strip and swatch black rather than transparent
* Delete dead code function
* Add a Gradient Interpolation axis with Stepped, Linear, and Smooth paths through the stops
* Keep the gradient interpolation attached when dragging stops in the picker
* Give the gradient popover's dropdowns the same tooltips as their row labels
* Order the gradient popover with Intrp. above Space
* Hold gradient stops in place when the cyclic flag is toggled
* Fix wrong Smooth gradient colors around stops sitting on the ramp boundaries
* Consolidate gradient settings plumbing and fix bugs
* Bundle whole-ramp gradient settings into GradientSettings across the editor plumbing
* Name the Smooth gradient interpolation's spline type in its tooltip
* Linearize the gamma hex stop colors recovered from imported Graphite SVGs
* Code review
* Aim the Smooth bake's seam subdivision at the copied boundary color
* Add GradientEvaluator to build gradient sampling state once per loop instead of per sample
* Correct the gradient evaluator's documented setup cost to O(n log n)
* Add a Cyclic gradient attribute that wraps the stop list through the 1|0 boundary back to the first stop
* Show the wrap segment's midpoint diamond in the color picker spectrum strip when cyclic
* Keep the wrap midpoint diamond tracking the pointer by a wrapped strip width when dragged past the ends
* Give the Gradient tool's viewport overlay the same cyclic wrap midpoint diamond and drag behavior
* Correct the docs claiming the final stop's midpoint is always ignored now that cyclic uses it
* Move the gradient cyclic toggle onto the Ends row as a Link icon checkbox
* Update labels
* Register GradientHueDirection with the Data panel so its attribute column renders
* Reword wrap segment to wrapped interval and stray segment usages to interval
* Clean up comments
* Fix the color picker write-back losing default position elision and the blend path guessing the cyclic flag
* Introduce the GradientRamp exchange struct as the serialized TaggedValue::Gradient payload
* Unify FillChoice and FillChoiceUI into one enum generic over color format, carrying GradientRamp stops
* Rename the TaggedValue::Gradient variant to GradientRamp to match its payload
* Move the Color variant into the tagged_value macro list since its stored and wire forms match
