/** \class SkBitmap
    SkBitmap describes a two-dimensional raster pixel array. SkBitmap is built on
    SkImageInfo, containing integer width and height, SkColorType and SkAlphaType
    describing the pixel format, and SkColorSpace describing the range of colors.
    SkBitmap points to SkPixelRef, which describes the physical array of pixels.
    SkImageInfo bounds may be located anywhere fully inside SkPixelRef bounds.

    SkBitmap can be drawn using SkCanvas. SkBitmap can be a drawing destination for SkCanvas
    draw member functions. SkBitmap flexibility as a pixel container limits some
    optimizations available to the target platform.

    If pixel array is primarily read-only, use SkImage for better performance.
    If pixel array is primarily written to, use SkSurface for better performance.

    Declaring SkBitmap const prevents altering SkImageInfo: the SkBitmap height, width,
    and so on cannot change. It does not affect SkPixelRef: a caller may write its
    pixels. Declaring SkBitmap const affects SkBitmap configuration, not its contents.

    SkBitmap is not thread safe. Each thread must have its own copy of SkBitmap fields,
    although threads may share the underlying pixel array.
