Hi,

this simple shadow patch has generated a long discussion on
Libreoffice-design. Some people don't like the color, some people don't
like the amount of blur, some people want no shadow at all, some people
want a "4 borders" shadow. So here is a second patchset that tries to
address the first three critics :
 - It adds a configuration option (in Appearance category) to set shadow
   color. It currently defaults to gray but I'm sure design team will
   find a more sensitive default :
 - It adds a configuration option to disable shadow;
 - It doesn't use bitmaps directly anymore but an alpha mask, so if
   people want to try another blur effect, they just have to edit
   images.zip:/sw/res/page-*-shadow-mask.png These are black & white
   image. Black amount determines transparency, white being fully
   transparent. Here again, I'm sure that design people will find a
   better default. Only constraints are 1x10px for bottom shadow,
   10x10px for corner and 10x1px for right shadow.
I'll let design team play and discuss with that, when they agree on a
default, I'll provide an additional patch to take it into account.

Note: I had to perform a make dev-install for settings to be correctly
saved.

Regards

Sébastien
