/* Convention/Type of settings. This will be merged mostly with the SaveLoad
 * SLE_ enums. So it looks a bit strange. The layout is as follows:
 * bits 0-7: the type (size) of the variable. Eg int8, uint8, bool, etc. Same as VarTypes
 * bits 8-15: the generic variable type. Eg string, oneofmany, number, intlist
 * bits 16-31: the size of a string, an intlist (which is an implicit array). */
