 These following graphics context method are provided to easily write cross-platform(AppKit/UIKit) code.
 For UIKit, these methods just call the same method in `UIGraphics.h`. See the documentation for usage.
 For AppKit, these methods use `NSGraphicsContext` to create image context and match the behavior like UIKit.
