Hi Knut,
Nice work on the videos. Just a couple quick thoughts.

I take it you have tried this?
#(define (color? ...) ...)
In the after-line-breaking function I give color the objects ... well,
not really:
I abuse the color property to encode the moment and duration of the
color change.
Would it help to define your own custom properties (grob or context) to
avoid overloading the color property. I have this in my include file
for Clairnote:
#(let*
;; translator-property-description function
;; from "scm/define-context-properties.scm" (modified)
((context-prop
(lambda (symbol type?)
(set-object-property! symbol 'translation-type? type?)
(set-object-property! symbol 'translation-doc "custom context
property")
(set! all-translation-properties (cons symbol
all-translation-properties))
symbol))
;; define-grob-property function
;; from "scm/define-grob-properties.scm" (modified)
(grob-prop
(lambda (symbol type?)
(set-object-property! symbol 'backend-type? type?)
(set-object-property! symbol 'backend-doc "custom grob property")
symbol)))
(context-prop 'myfoo list?)
(grob-prop 'mybar integer?)
;; etc...
)
Then I can use my custom properties just like the built-in ones.
