21 * @brief Container for a single image from a picture asset.
30 * @brief A single frame of picture data held in an ARGB buffer.
32 * The format of the data is:
35 * Byte /- 0 -------|- 1 --------|- 2 --------|- 3 --------|- 4 --------|- 5 --------| ...
36 * |(0, 0) Blue|(0, 0) Red |(0, 0) Blue |(0, 0) Alpha|(0, 1) Blue |(0, 1) Red | ...
39 * So that the first byte is the blue component of the pixel at x=0, y=0, the second
40 * is the red component, and so on.
42 * Lines are packed so that the second row directly follows the first.
