static Evas_Object add_image(char *filename, int x, int y) {
Evas_Object o;
o = evas_add_image_from_file(evas, filename);
evas_set_further_color(evas, o, plugin_read_color("basecolor"));

A tip on Evas (which I didn't expect you to know, so I'll just say it
here):
if you set the "color" of an image object, what it actually does is
sorta filter the image. This is handy because you can tweak the alpha
and get transparent images...
But in most cases, you don't want to set the color to basecolor, because
the user might have picked a color like green and you don't want your
images to be filtered to green.
The exception is seen in buttons in the XMMS plugin: here, I have
completely white images so that they filter properly by any color you
choose...

It looks pretty good, though that weirdness with dup() and such is
pretty crazy.
I'm amazed that people have managed to decipher the further API... :)
I can't test this code, though. Has anyone else used it?
I'd think further would be too processor-intensive (battery-intensive) to
run on a laptop. :)
I'll add it to the CVS with a few cleanups (copyright should be either
you or me, Ed just wrote one of the plugins :P).
