// Sprites are patches with a special naming convention so they can be
// recognized by R_InitSprites. The base name is NNNNFx or NNNNFxFx, with
// x indicating the rotation, x = 0, 1-7. The sprite and frame specified
// by a thing_t is range checked at run time.
// A sprite is a patch_t that is assumed to represent a three dimensional
// object and may have multiple rotations pre drawn. Horizontal flipping
// is used to save space, thus NNNNF2F5 defines a mirrored patch.
// Some sprites will only have one picture used for all views: NNNNF0
