Make shadows pretty and configurable The current shadow code just uses a single fixed texture (the Gaussian blur of a rectangle with a fixed blur radius) for drawing all window shadows. This patch adds the ability * Implement efficient blurring of arbitrary regions by approximating a Gaussian blur with multiple box blurs. * Detect when multiple windows can use the same shadow texture by converting their shape into a size-invariant MetaWindowShape. * Add properties shadow-radius, shadow-x-offset, shadow-y-offset, shadow-opacity to allow the shadow for a window to be configured. * Add meta_window_actor_paint() and draw the shadow directly from there rather than using a child actor. * Remove TidyTextureFrame, which is no longer used https://bugzilla.gnome.org/show_bug.cgi?id=592382

Export the shadow factory The elementary guys would like this as an API, and I don't see any reason to refuse -- this is quite nice shadow painting code :) For some reason, gobject-introspection can't seem to cope with MetaWindowShape. I'll look into it a bit later, but for now, mark the function it has trouble with as (skip).
