Whenever possible, prefer the safe wrappers withWindowAttributes or
safeGetWindowAttributes to getWindowAttributes.
Places where these are not applicable are limited to layouts, where
there is not good "default value" to give back in case these calls fail.
In these cases, we let the exception handling of the layout mechanism
handle it and fall back to the Full layout.

This is a convenience module in order to have less import noise. It
re-exports the following:
a) Commonly used modules in full (Data.Foldable, Data.Applicative, and
so on); though only those that play nicely with each other, so that
XMonad.Prelude can be imported unqualified without any problems.
This prevents things like `Prelude.(.)` and `Control.Category.(.)`
fighting with each other.
b) Helper functions that don't necessarily fit in any other module;
e.g., the often used abbreviation `fi = fromIntegral`.
This patch ensures that the focus (or in fact the whose windowset)
does not change as a result of a banishScreen. The way this is implemented
will become problematic if xmonad ever goes multithreaded.
warp 1 1 has a comment claiming that this moves the cursor to the lower *left*, but if you look at the warpToWindow haddock, it says that 1 1 is actually lower *right* - as indeed it proved to do. This was annoying as it led me astray for a minute or so.
