+ * # CategoryPixels
+ *
+ * SDL offers facilities for pixel management.
+ *
+ * Largely these facilities deal with pixel _format_: what does this set of
+ * bits represent?
+ *
+ * If you mostly want to think of a pixel as some combination of red, green,
+ * blue, and maybe alpha intensities, this is all pretty straightforward, and
+ * in many cases, is enough information to build a perfectly fine game.
+ *
+ * However, the actual definition of a pixel is more complex than that:
+ *
+ * Pixels are a representation of a color in a particular color space.
+ *
+ * The first characteristic of a color space is the color type. SDL
+ * understands two different color types, RGB and YCbCr, or in SDL also
+ * referred to as YUV.
+ *
+ * RGB colors consist of red, green, and blue channels of color that are added
+ * together to represent the colors we see on the screen.
+ *
+ * https://en.wikipedia.org/wiki/RGB_color_model
+ *
+ * YCbCr colors represent colors as a Y luma brightness component and red and
+ * blue chroma color offsets. This color representation takes advantage of the
+ * fact that the human eye is more sensitive to brightness than the color in
+ * an image. The Cb and Cr components are often compressed and have lower
+ * resolution than the luma component.
+ *
+ * https://en.wikipedia.org/wiki/YCbCr
+ *
+ * When the color information in YCbCr is compressed, the Y pixels are left at
+ * full resolution and each Cr and Cb pixel represents an average of the color
+ * information in a block of Y pixels. The chroma location determines where in
+ * that block of pixels the color information is coming from.
+ *
+ * The color range defines how much of the pixel to use when converting a
+ * pixel into a color on the display. When the full color range is used, the
+ * entire numeric range of the pixel bits is significant. When narrow color
+ * range is used, for historical reasons, the pixel uses only a portion of the
+ * numeric range to represent colors.
+ *
+ * The color primaries and white point are a definition of the colors in the
+ * color space relative to the standard XYZ color space.
+ *
+ * https://en.wikipedia.org/wiki/CIE_1931_color_space
+ *
+ * The transfer characteristic, or opto-electrical transfer function (OETF),
+ * is the way a color is converted from mathematically linear space into a
+ * non-linear output signals.
+ *
+ * https://en.wikipedia.org/wiki/Rec._709#Transfer_characteristics
+ *
+ * The matrix coefficients are used to convert between YCbCr and RGB colors.

+ * Pixel format.
+ *
+ * SDL's pixel formats have the following naming convention:
+ *
+ * - Names with a list of components and a single bit count, such as RGB24 and
+ *   ABGR32, define a platform-independent encoding into bytes in the order
+ *   specified. For example, in RGB24 data, each pixel is encoded in 3 bytes
+ *   (red, green, blue) in that order, and in ABGR32 data, each pixel is
+ *   encoded in 4 bytes (alpha, blue, green, red) in that order. Use these
+ *   names if the property of a format that is important to you is the order
+ *   of the bytes in memory or on disk.
+ * - Names with a bit count per component, such as ARGB8888 and XRGB1555, are
+ *   "packed" into an appropriately-sized integer in the platform's native
+ *   endianness. For example, ARGB8888 is a sequence of 32-bit integers; in
+ *   each integer, the most significant bits are alpha, and the least
+ *   significant bits are blue. On a little-endian CPU such as x86, the least
+ *   significant bits of each integer are arranged first in memory, but on a
+ *   big-endian CPU such as s390x, the most significant bits are arranged
+ *   first. Use these names if the property of a format that is important to
+ *   you is the meaning of each bit position within a native-endianness
+ *   integer.
+ * - In indexed formats such as INDEX4LSB, each pixel is represented by
+ *   encoding an index into the palette into the indicated number of bits,
+ *   with multiple pixels packed into each byte if appropriate. In LSB
+ *   formats, the first (leftmost) pixel is stored in the least-significant
+ *   bits of the byte; in MSB formats, it's stored in the most-significant
+ *   bits. INDEX8 does not need LSB/MSB variants, because each pixel exactly
+ *   fills one byte.
+ *
+ * The 32-bit byte-array encodings such as RGBA32 are aliases for the
+ * appropriate 8888 encoding for the current platform. For example, RGBA32 is
+ * an alias for ABGR8888 on little-endian CPUs like x86, or an alias for
+ * RGBA8888 on big-endian CPUs.
