Canal ids

The used item ID defines what sprites this item provides. Item IDs should be picked from the following table (WF_XXX).

The 'normal sprites' column contains the amount of sprites that should be provided for this feature. If the appropriate bit in the graphics_flags-property (see below) the amount of sprites stated in the 'alternative sprites' column must be provided instead.
