O(1). Use a ForeignPtr of RGBA data as a bitmap with the given width and height.

bitmapOfByteString :: Int -> Int -> ByteString -> Bool -> Picture

O(size). Copy a ByteString of RGBA data into a bitmap with the given width and height.

O(size). Copy a BMP file into a bitmap.

loadBMP :: FilePath -> IO Picture
