They used a simple bimap. Their approach is more or less the same as
the first implementation I did (when no color configuration was
possible), except they just use one bitmap that they split at
predefined positions instead of having one bitmap per side/corner.

I guess the current impress shadow should be nice on any background
since there is an alpha channel and no area has a full opacity…

I can't find the mail about the document corners… I attached you the
bitmap used in impress to draw the shadow.

I think we'll have to test how gradients can be used to get a nice
background. Keeping in mind that current gradient implementation
focuses on performances rather than on quality…

I'll try to quickly implement and push impress shadow to sw so you can
see the result throught the nightlies
