* To make a new render mode (the C part, at least):

* you need any extra objects that are easy to create in python, this
* is where you put them.
*
* * fill in this interface struct in rendermode-(yourmode).c
* (see rendermodes-normal.c for an example: the "normal" mode)
* * create a file in src/primitives with the same name
* so, Nether (named "nether") goes in `nether.c`.
*
* * if you want to derive from (say) the "normal" mode, put
* a RenderModeNormal entry at the top of your data struct, and
* be sure to call your parent's functions in your own!
* (see rendermode-night.c for a simple example derived from
* the "lighting" mode)
* * declare a RenderPrimitiveInterface with the name primitive_name
* if you have an underscore in the name, replace it with a
* hyphen. height-fading uses primitive_height_fading.
*
* * add your mode to the list in rendermodes.c
* * fill in the entries of this struct
* the name should match, and you should declare an 'instance' struct
* to use as the self argument to each function. See nether.c and
* height-fading.c for simple examples.
*
* setup.py will pick up your primitive, add it to the global list, and build
* it for you if you follow these conventions.
