styleMask specifies the receiver's style. It can either be
NSBorderlessWindowMask, or it can contain any of the following
options, combined using the C bitwise OR operator: Option Meaning
NSTitledWindowMask The NSWindow displays a title bar.
NSClosableWindowMask The NSWindow displays a close button.
NSMiniaturizableWindowMask The NSWindow displays a miniaturize button.
NSResizableWindowMask The NSWindow displays a resize bar or border.

NSClosableWindowMask 2
NSMiniaturizableWindowMask 4
NSResizableWindowMask 8
NSIconWindowMask 64
NSMiniWindowMask 128
Borderless windows display none of the usual peripheral elements and
are generally useful only for display or caching purposes; you
should normally not need to create them. Also, note that an
NSWindow's style mask should include NSTitledWindowMask if it
includes any of the others.
backingType specifies how the drawing done in the receiver is
buffered by the object's window device: NSBackingStoreBuffered
NSBackingStoreRetained NSBackingStoreNonretained
flag determines whether the Window Server creates a window device
for the new object immediately. If flag is YES, it defers creating
the window until the receiver is moved on screen. All display
messages sent to the NSWindow or its NSViews are postponed until the
window is created, just before it's moved on screen. Deferring the
creation of the window improves launch time and minimizes the
virtual memory load on the Window Server. The new NSWindow creates
an instance of NSView to be its default content view. You can
replace it with your own object by using the setContentView: method.
