/**
* \file effects.h "Special effects" other than compositor effects.
*
* Before we had a serious compositor, we supported swooping
* rectangles for minimising and so on. These are still supported
* today, even when the compositor is enabled. The file contains two
* parts:
*
* 1) A set of functions, each of which implements a special effect.
* (Only the minimize function does anything interesting; we should
* probably get rid of the rest.)
*
* 2) A set of functions for moving a highlighted wireframe box around
* the screen, optionally with height and width shown in the middle.
* This is used for moving and resizing when reduced_resources is set.
*
* There was formerly a system which allowed callers to drop in their
* own handlers for various things; it was never used (people who want
* their own handlers can just modify this file, after all) and it added
* a good deal of extra complexity, so it has been removed. If you want it,
* it can be found in svn r3769.
