gets my vote. i hadn't thought of GKeyFile.

this is a tricky one. you probably see that because the knob anim
was created with unsuitable rendering options.

there are also two different cases here. animations for use against a
dynamic
themed bg and animations created for use against a static (pixmap or
themed) bg.
if you specify a static bg then the makeup of rendered shadows doesn't
matter
much as you can see right away how well they work. but for use with gtk
themes
you need black shadows tempered by the alpha (not grey scale or colour
tinted
shadows) in order to get consistently good results across all possible
colours.

if you want then i won't object but if i understand you
correctly then it's still going to look powerful ugly on a dark
theme anyway right?

not only would i encourage people to (re)render their animations
with black shadows and alpha but i'll personally commit to doing
so for anyone who asks (where possible).

i'd suggest using frames instead of num_pixmaps. it makes sense in the
context of an animation and most of the gtkknob implementations seem to
have settled on drawing from an offset within the original image rather
than chopping it up into separate images and putting them into a GList.

a version tag for future extension of the spec without screwing up the
legacy?

WRT the galan knob animation, is the source available? i asked you a
year or 2 back and i can't remember why it wasn't then. nor can i
remember what it was created with, but if it was blender, look in the
scene tab, in the render block and at the bottom, select the "Premul"
option and rerender the sequence. the background and shadows should
appear black in the render window. see if that helps with the shadows.
if you can get me the source then i'd be happy to do it too.

cheers,
pete.
