-// A device is basically a wrapper around SkBitmap that provides a surface for
-// SkCanvas to draw into. Our device provides a surface CoreGraphics can also
-// write to. BitmapPlatformDevice creates a bitmap using
-// CGCreateBitmapContext() in a format that Skia supports and can then use this
-// to draw text into, etc. This pixel data is provided to the bitmap that the
-// device contains so that it can be shared.
-//
-// The device owns the pixel data, when the device goes away, the pixel data
-// also becomes invalid. THIS IS DIFFERENT THAN NORMAL SKIA which uses
-// reference counting for the pixel data. In normal Skia, you could assign
-// another bitmap to this device's bitmap and everything will work properly.
-// For us, that other bitmap will become invalid as soon as the device becomes
-// invalid, which may lead to subtle bugs. Therefore, DO NOT ASSIGN THE
-// DEVICE'S PIXEL DATA TO ANOTHER BITMAP, make sure you copy instead.
