[Fluxus] typeprimitive memory leak

[gabor papp]

i found a possible memory leak in typeprimitive, the
used typeface and library were not destroyed, but it seems it is still
leaking somewhere. running the following script slowly eats up the memory.

(clear)

(define type 0)

(define (animate)
    (destroy type)
    (set! type (build-type "Bitstream-Vera-Sans-Mono.ttf" "test")))

(every-frame (animate))

best,
gabor
