hi tim.

thanks for the code.
i am still wondering whether it wouldn't be better to make this 
behaviour with a new (and working) version of [pix_resize] and 
[pix_dump] (i mean: if [pix_resize] would take arguments for the new 
size and this size could be 1x1 *and* the resizing would do 
interpolation than this would do almost the same as [pix_analyse_colors] 
(i think it is rather [pix_mean_color], but who cares) and it would be 
more flexible (finally the object we need to mix/merge/... images of 
different sizes)

we could then have a look at performance and eventually include it as an 
abstraction.

but thanks anyhow.
btw, have you tested the greyscale code ?

this is possible (but in this case you haveis quite an elementary object 
that should rather go into Gem itself)
under linux it is simple, on windows you probably now better than me 
(when i started to compile my own Gem objects i didn't bother to make 
them separate externals but rather built my whole Gem++, just because i 
was to lazy/stupid; later i became maintainer and the problem was gone)
