xpanning allows you to pan, or shift, the image of a sprite the same way you would pan a ceiling, floor, or wall texture along the x axis. Values are normalized on a 0-255 scale, meaning that regardless of the sprite's size, a value of 128 will pan it 50%.
The CON wall[].xpanning refers to the struct member of the wall structure.
The CON actor[].xpanning field refers to the struct member of the spriteext structure (the sprite structure doesn't have such a member). Since spriteext is only used in the OpenGL renderers, it has no effect on classic mode; moreover, spriteext xpanning is only implemented for Polymost as of December 2011. When used on a sprite with a model assigned to it in Polymost mode, xpanning controls the model's texture UV map position.
