/**
 * Performs a Y2R colorspace conversion.
 *
 * The Y2R hardware implements hardware-accelerated YUV to RGB colorspace conversions. It is most
 * commonly used for video playback or to display camera input to the screen.
 *
 * The conversion process is quite configurable, and can be divided in distinct steps. From
 * observation, it appears that the hardware buffers a single 8-pixel tall strip of image data
 * internally and converts it in one go before writing to the output and loading the next strip.
 *
 * The steps taken to convert one strip of image data are:
 *
 * - The hardware receives data via CDMA (http://3dbrew.org/wiki/Corelink_DMA_Engines), which is
 *   presumably stored in one or more internal buffers. This process can be done in several separate
 *   transfers, as long as they don't exceed the size of the internal image buffer. This allows
 *   flexibility in input strides.
 * - The input data is decoded into a YUV tuple. Several formats are suported, see the `InputFormat`
 *   enum.
 * - The YUV tuple is converted, using fixed point calculations, to RGB. This step can be configured
 *   using a set of coefficients to support different colorspace standards. See `CoefficientSet`.
 * - The strip can be optionally rotated 90, 180 or 270 degrees. Since each strip is processed
 *   independently, this notably rotates each *strip*, not the entire image. This means that for 90
 *   or 270 degree rotations, the output will be in terms of several 8 x height images, and for any
 *   non-zero rotation the strips will have to be re-arranged so that the parts of the image will
 *   not be shuffled together. This limitation makes this a feature of somewhat dubious utility. 90
 *   or 270 degree rotations in images with non-even height don't seem to work properly.
 * - The data is converted to the output RGB format. See the `OutputFormat` enum.
 * - The data can be output either linearly line-by-line or in the swizzled 8x8 tile format used by
 *   the PICA. This is decided by the `BlockAlignment` enum. If 8x8 alignment is used, then the
 *   image must have a height divisible by 8. The image width must always be divisible by 8.
 * - The final data is then CDMAed out to main memory and the next image strip is processed. This
 *   offers the same flexibility as the input stage.
 *
 * In this implementation, to avoid the combinatorial explosion of parameter combinations, common
 * intermediate formats are used and where possible tables or parameters are used instead of
 * diverging code paths to keep the amount of branches in check. Some steps are also merged to
 * increase efficiency.
 *
 * Output for all valid settings combinations matches hardware, however output in some edge-cases
 * differs:
 *
 * - `Block8x8` alignment with non-mod8 height produces different garbage patterns on the last
 *   strip, especially when combined with rotation.
 * - Hardware, when using `Linear` alignment with a non-even height and 90 or 270 degree rotation
 *   produces misaligned output on the last strip. This implmentation produces output with the
 *   correct "expected" alignment.
 *
 * Hardware behaves strangely (doesn't fire the completion interrupt, for example) in these cases,
 * so they are believed to be invalid configurations anyway.
