-// A device is basically a wrapper around SkBitmap that provides a surface for |
-// SkCanvas to draw into. Our device provides a surface Windows can also write |
-// to. BitmapPlatformDevice creates a bitmap using CreateDIBSection() in a |
-// format that Skia supports and can then use this to draw ClearType into, etc. |
-// This pixel data is provided to the bitmap that the device contains so that it |
-// can be shared. |
-// |
-// The GDI bitmap created for drawing is actually owned by a |
-// PlatformBitmapPixelRef, and stored in an SkBitmap via the normal skia |
-// SkPixelRef refcounting mechanism. In this way, the GDI bitmap can outlive |
-// the device created to draw into it. So it is safe to call accessBitmap() on |
-// the device, and retain the returned SkBitmap. |
