This method handles all normal displaying. It is set to be run on each
runloop iteration for each window that's on-screen. The performer is
added then the window is ordered in and re-added each time it is run.
If the window is ordered out, the performer is cancelled.
The reason why this performer is always added, as opposed to adding it
when display is needed and not re-adding it here, is that
-setNeedsDisplay* might be called from a method invoked by
-performSelector:target:argument:order:modes:, and if it is, the display
needs to happen in the same runloop iteration, before blocking for
events. If the performer were added in a call to another performer, it
wouldn't be called until the next runloop iteration, ie. after the runloop
has blocked and waited for events.

/**
<unit>
<heading>NSWindow</heading>
<p> Instances of the NSWindow class handle on-screen windows, their
associated NSViews, and events generate by the user. An NSWindow's
size is defined by its frame rectangle, which encompasses its entire
structure, and its content rectangle, which includes only the
content.
</p>
<p> Every NSWindow has a content view, the NSView which forms the
root of the window's view hierarchy. This view can be set using the
<code>setContentView:</code> method, and accessed through the
<code>contentView</code> method. <code>setContentView:</code>
replaces the default content view created by NSWindow.
</p>
<p> Other views may be added to the window by using the content
view's <code>addSubview:</code> method. These subviews can also
have subviews added, forming a tree structure, the view hierarchy.
When an NSWindow must display itself, it causes this hierarchy to
draw itself. Leaf nodes in the view hierarchy are drawn last,
causing them to potentially obscure views further up in the
hierarchy.
</p>
<p> A delegate can be specified for an NSWindow, which will receive
notifications of events pertaining to the window. The delegate is
set using <code>setDelegate:</code>, and can be retrieved using
<code>delegate</code>. The delegate can restrain resizing by
implementing the <code>windowWillResize: toSize:</code> method, or
control the closing of the window by implementing
<code>windowShouldClose:</code>.
</p>
