AppleFood constructor: sets type to APPLE

Constructor: Initializes the board with the given level data

Constructor: loads and resizes the button image, then creates a texture

Draws the given food object using the appropriate texture or a red rectangle if type is unknown

Draws the board and its cells

Draws the background rectangle for the board

Draws the snake's body segments, choosing the correct texture for straight or turning segments.

Draws the snake's head using the correct texture based on the current direction.

Draws a single part of the snake (head, body, or tail) at the specified board position.

Draws the snake's tail using the correct texture based on the direction of the last segment.

Constructor: Loads images and creates textures for each food type
