Fixed stale references to neomacs effects functions that have been renamed or no longer exist - #686
Numerous areas in the code referenced previous implementation of effects-setting which is no longer in use (pre-setopts).
Summary by cubic
Fixes stale references to the removed effects functions (neomacs-effect-set, neomacs-effect-reset, neomacs-effects-apply) so the showcase and doc comments no longer reference or call APIs that no longer exist.
Migrates the showcase to the defcustom-based option interface (setopt, customize-set-variable, custom-reevaluate-setting), fixing void-function errors from the first section.
Renames private primitives to neomacs--effect-set / neomacs--effects-apply in Rust comments.
Corrects doc comments that suggested setq for renderer options, since a plain setq changes only the variable and never reaches the renderer.
Drops cubic-bezier from buffer and scroll easing options, where it previously ran silently as linear because the configs have nowhere to store control points.
Written for commit 7d1b163. Summary will update on new commits.

Walkthrough
The changes update effect configuration guidance and command references. The showcase applies effects through option setters, synchronizes option values with renderer state, and restores saved values when the demo ends. Buffer and scroll transition easing choices no longer include cubic-bezier.
Comments and documentation explain how setopt, Customize, and setq interact with effect options. Examples use individual effect options and current internal command names. Buffer and scroll transition easing choices no longer include cubic-bezier.
The showcase captures and restores option and renderer values. Demo effects use option setters and helpers, and resets apply defaults while syncing option values.

Correct the setq note in the buffer transition comment.
A setq made before neomacs-effects.el loads reaches the renderer. defcustom calls the :set function with that value at load, so the note applies only to a setq made after load.

made after `neomacs-effects.el` loads does not reach the renderer; preserve the
distinction that a pre-load value reaches the renderer through `defcustom`’s
`:set` function.

- Line 319: Update showcase--effect-reset so it disables the gallery effect
regardless of its saved value, rather than reapplying that value through
custom-reevaluate-setting. Use the established setting mechanism for the effect
option and preserve the behavior of resetting the renderer to the disabled
state.
- Line 336: Update showcase--reset-all-effects so every neomacs-effect-* option
enabled by a gallery section is reset to its disabled Customize value through
the established option-setting path, keeping the option values synchronized with
the state reset by neomacs--effects-apply. Identify all affected options across
the showcase rather than updating only neomacs-effect-cursor-color-cycle.

🟡 Changes recommended
A moderate active finding notes that an optional require for neomacs-effects can silently skip loading the defcustoms needed for setopt to trigger renderer-related :set functions, risking degraded or incorrect showcase behavior unless it fails loudly when those primitives are expected.
This pull request updates Neomacs’ showcase code and in-source comments to align with the current defcustom/setopt-based effects configuration flow, replacing stale references to removed/renamed effects functions and reflecting the private neomacs--* primitives.
Changes:
Migrates the effects showcase away from removed neomacs-effect-* / neomacs-effects-apply calls to setopt/Customize workflows (and internal apply where needed).
Updates Elisp/Rust comments and tests to reference renamed private primitives (e.g., neomacs--effect-set, neomacs--effects-apply) and clarifies that plain setq won’t invoke renderer-updating :set hooks.
Removes unsupported cubic-bezier easing choices from buffer/scroll options where control points cannot be represented.
This pull request requires changes.

- Around line 13-14: Update the cursor-glow settings guidance around
neomacs-effect-cursor-glow to explain that each assignment replaces the saved
option plist even if the renderer retains omitted properties. Advise users to
include every desired property in each assignment or merge new properties with
the existing plist so settings such as :enabled persist after saving and
restarting.
- Around line 38-39: Update the cursor-blink documentation around the neomacs
cursor settings to explain that neomacs--setup-cursor-blink overwrites them at
startup from blink-cursor-mode and blink-cursor-interval. Direct users to
configure those standard settings for persistent blink behavior.

neomacs-effects-apply, neomacs-effect-set and neomacs-effect-reset were
removed when effects became defcustoms, so the showcase signalled
void-function from its first section.
Set gallery and behavioural options with setopt. Use customize-set-variable
and custom-reevaluate-setting where the effect is only known at run time,
which is the Custom path the removal commit named as the replacement for
reset. Keep neomacs--effects-apply for whole profiles, which no option
expresses.
Also drop the removed effects profile from the neomacs-cursor-effect
docstring.
Options reach the renderer only through :set, so setq on a loaded option
changes the variable alone: in a batch run, scroll-transition stayed
disabled after setq and turned on after setopt. Correct the commentary and
the two transition defaults that suggested setq, rather than add watchers.
A watcher on 210 options would also fire on let-binding and on the
set-default inside every :set, and setq on a :set option does nothing in
GNU Emacs either.
Rename the private primitives in Rust comments and drop the removed
neomacs-effects profile.
neomacs-webkit-create is not registered by any crate, so every artifact
reported webview as false. xwidget-internal is what the runtime provides
when the webview backend is present.
BufferTransitionConfig and ScrollTransitionConfig have nowhere to store
control points, so choosing cubic-bezier silently ran as linear. The window
and child-frame slots keep the choice because they carry the points.
The showcase turned gallery effects on with customize-set-variable and
put them back with custom-reevaluate-setting. The first records a
customization; the second reapplies a saved value, so leaving an effect
turned a saved one back on. Section resets published a clean renderer
through neomacs--effects-apply and left the options at the demo values.
Remember the renderer and the option values before the first change.
Drive the demo through each option's :set function, and on quit write
the snapshot back with set-default so neither customized-value nor a
saved value is involved.

neomacs-effect-set, neomacs-effect-reset, and neomacs-effects-apply are
not defined. The animation page linked from the README, EFFECTS.md, and
the display-engine pipeline still called them. Describe setopt, and say
that a setq reaches the renderer only when it is made before
neomacs-effects.el loads.

showcase--apply-profile merges, so each atmosphere preset left the
previous one enabled. Clear the demo slate before a preset, then apply
it through the option setters.
Require neomacs-effects when the renderer subr exists. Document that a
gallery setopt replaces the option plist while the renderer merges, and
that cursor blink follows blink-cursor-mode rather than those options.
