vector typing

[Dave Griffiths]

Hi all,

I'm upgrading an application from the old gh interface (yep, about time
too, it's much nicer) and I've noticed a change in the way vectors are
constructed in the api. I used to use gh_doubles2scm to quickly convert a
block of data into a generalised vector. I've moved over to using
scm_take_f32vector, which is just as fast, but creates vectors which have
to be accessed by (f32vector-ref) etc.

I admit I am confused about the typing of vectors - is there a quick way
to create generalised vectors other than using scm_make_vector and adding
each element individually with scm_vector_set_x?

Speed is an issue, as this is a graphics application
(http://www.pawfal.org/fluxus) and I'm doing a lot of things with vectors.
Are f32 better for speed reasons anyway? Why can't I access them with the
vanilla vector-ref/vector-set! etc?

cheers,

dave
