Controlling "Animate windows when minimizing and maximizing" from script

One user wanted to know how to configure the "Animate windows when minimizing and maximizing" performance setting from the command line. There is a Registry entry that directly represents that checkbox, but tweaking that value doesn't cause a behavior change until after a logon/logoff cycle. The correct way to programmatically adjust the setting is via the SystemParametersInfo function, so this calls for some PowerShell and P/Invoke. (It would be a great opportunity to showcase my P/Invoke command-line tool, but it's not ready for release yet.) The call is made somewhat tricky by the need for a special structure, so jamming the entire thing into one PowerShell run would be unwieldy, but it's fine as a script:

Add-Type -TypeDefinition @"
    using System;
    using System.Runtime.InteropServices;
    [StructLayout(LayoutKind.Sequential)] public struct ANIMATIONINFO {
        public uint cbSize;
        public bool iMinAnimate;
    }
    public class PInvoke { 
        [DllImport("user32.dll")] public static extern bool SystemParametersInfoW(uint uiAction, uint uiParam, ref ANIMATIONINFO pvParam, uint fWinIni);
    }
"@
$animInfo = New-Object ANIMATIONINFO
$animInfo.cbSize = 8
$animInfo.iMinAnimate = $args[0]
[PInvoke]::SystemParametersInfoW(0x49, 0, [ref]$animInfo, 3)

It takes a Boolean value specifying whether to enable window minimize/restore animations.
