TODO: <a href="https://golang.org/cl/36734">https://golang.org/cl/36734</a>: fix the overlap check in Rectangle.Intersect.
The <a href="/pkg/image/#Rectangle.Intersect"><code>Rectangle.Intersect</code></a>
method now returns a zero <code>Rectangle</code> when called on
adjacent but non-overlapping rectangles, as documented. In
earlier releases it would incorrectly return an empty but
non-zero <code>Rectangle</code>.

The YCbCr to RGBA conversion formula has been tweaked to ensure

TODO: <a href="https://golang.org/cl/34150">https://golang.org/cl/34150</a>: reduce memory allocs encoding images by reusing buffers
The new <a href="/pkg/image/png/#Encoder.BufferPool"><code>Encoder.BufferPool</code></a>
field allows specifying an <a href="/pkg/image/png/#EncoderBufferPool"><code>EncoderBufferPool</code></a>,
that will be used by the encoder to get temporary <code>EncoderBuffer</code>
buffers when encoding a PNG image.
The use of a <code>BufferPool</code> reduces the number of
memory allocations performed while encoding multiple images.
