YES if the layer contents are implicitly flipped when rendered or
NO if they are not. This method returns
NO by default.
This method provides information about whether the layer’s contents are being flipped during drawing. You should not attempt to override this method and return a different value.
If the layer needs to flip its content, it returns
YES from this method and applies a y-flip transform to the graphics context before passing it to the layer’s
draw method. Similarly, the layer converts any rectangles passed to its
set into the flipped coordinate space.
