Just making a brief commit and thats all to add onto dj's lighting engine improvements because I heard about the PR, in mine I
* allowed all Vtx objects to be manipulated/retrieved
* updated lighting engine demo to be an SM64 night mode with a flashlight
* Fixed longterm bug where lighting bugs out unless you spawn a light
* Added new default LE mode LE_MODE_AFFECT_ALL_SHADED_AND_COLORED which also affects vertex colored surfaces
* set_gfx_command part 2
* part 3
* get gfx/vtx from name; copy gfx/vtx
* gfx/vtx dynamic allocation lua
* gfx/vtx_new: don't take level/model/vanilla names
* Clean up gbi constants
* update example
* Isaac review; add gfx_get_next_command and vtx_get_next_vertex
* make all commands length 1; missing NULL checks
* CONCEPT: Basic vertex lighting engine
Set the geometry mode on your model to G_LIGHTING_ENGINE_EXT, spawn a `bhvAmbientLight`, spawn some `bhvPointLight`s, and then you got yourself a mighty interesting scene.
* Fixes
* How did I miss this
* Make light set home pos
