Note that the use of the DrawTextureWithTexCoords function and not the standard
DrawTexture function is normally preferred in GUI drawing. This is because we are
selecting the texture to be drawn from our spritesheet and we have to use scaled coordin-
ates to pick the image as that is what the function uses. The Rect coordinates used in the
Sprite object's textureRect property (the picking coordinates) are unscaled.
