Some backends need to know the native context to do their thing in virtual Reindeer functions. The function ren_reindeer_new should take a void pointer whose meaning is backend specific. The application needs to look up in the reference documentation what it is supposed to point to here (backend specific headers could help here). It is recommended that backends make it easy for themselves to change the meaning of this pointer while still allowing old code to use the old meaning (binary compatibility). In practice this means making the pointer point to a struct where the first field is an integer specifying the version of the rest of the struct.
