A collection of pixels used in software blitting.
Pixels are arranged in memory in rows, with the top row first. Each row occupies an amount of memory given by the pitch (sometimes known as the row stride in non-SDL APIs).
Within each row, pixels are arranged from left to right until the width is reached. Each pixel occupies a number of bits appropriate for its format, with most formats representing each pixel as one or more whole bytes (in some indexed formats, instead multiple pixels are packed into each byte), and a byte order given by the format. After encoding all pixels, any remaining bytes to reach the pitch are used as padding to reach a desired alignment, and have undefined contents.
