We now hijack existing system functions to integrate with `WinMgr`, instead of `Spawn`ing our own `SaphirTask`. Also, you can now use `Saphir(Bool)` to toggle enable/disable the features. There is a global var `saphir` which values are set by `Defaults.HC` for colors and other behaviors; these values can be changed at any time.
