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
* Lighting engine improvements
Now objects will be affected by the lighting engine. This is
accomplished by passing the renderer the object's model matrix
(uncombined with the view or projection). You can now setup the
lighting engine mode to affect all shaded surfaces, lighting can
be affected by surface normals, and you can control what type of
tone mapping is applied.
added le_set_mode(mode)
By default we retain the previous behavior.
When set to LE_MODE_AFFECT_ALL_SHADED the lighting engine will
affect every shaded material.
This way we don't have to recompile every object and level that
we want shaded with special coop-specific commands
added le_get_mode()
added le_set_tone_mapping(toneMapping)
Tone mapping is what happens when a color value exceeds its 0-255
range.
By default we retain the current tone mapping (called
LE_TONE_MAPPING_TOTAL_WEIGHTED).
LE_TONE_MAPPING_WEIGHTED is now accessible, it was the tone
mapping that was previously left out of the compile through ifdefs.
LE_TONE_MAPPING_CLAMP is just simple additive with a clamp at a
color value of 255.
LE_TONE_MAPPING_REINHARD is reinhard tone mapping
(vout = (vin + 1) / vin).
added le_set_light_use_surface_normals(id, useSurfaceNormals)
By default lights retain their previous behavior (of ignoring
surface normals).
When enabled lights cast on one side of the object will not
appear on the other side of the object.
It is kind of like backface culling, but for lights.
added le_calculate_lighting_color_with_normal(pos, normal, outColor, lightIntensityScalar)
It's just like le_calculate_lighting_color(), but you can pass
in normals now.
* Removed normal calculation from vertex colored surfaces - they don't have normals
* Use packed normals correctly
* made LE_MODE_AFFECT_ALL_SHADED the default
* made useSurfaceNormals the default for lights
* Set ambient color, performed le_is_enabled() checks
The ambient color was black, which is why everything was dark by default.
If we set ambient to white then people will never see the effects of their
lights unless they set ambient to a lower value. So I added checks for
if a light has ever been added. The alternative would be to have something
like le_set_enabled()
* Rewrite how we obtain the model matrix - invert the camera
* run autogen
* Change default tonemapper to weighted, make setting ambient enable LE, fix null deref
* Address Peachy's comments

There was a bug in resolving wall collisions with fixCollisionBugsRoundedCorners enabled.
Due to the way a check was written, it would often ignore walls when it shouldn't have.
I've also added gLevelValues.floorNormalMinY and gLevelValues.ceilNormalMaxY
These will values will be used to determine which surfaces will become a wall, floor, or ceiling

I didn't add standard Lua require() because I've always been
afraid of it. I'm not sure we can guarantee which files it
will read (or not read).
Instead, here is a custom implementation. It should work more
or less the same and allow for more modular code.
For backwards compatibility reasons, all of the lua files in
the base mod folder will be loaded as in the past. Aka one at
a time and alphabetically.
However, now coop will look for Lua files in subdirectories
and will load them in when another Lua file calls require().
The file search order is more reasonable than normal Lua
require(). It will first look for files relative to the
currently running script. If there is no matching relative
file, it will pick from any Lua file that is in any of the
mod's subdirectories.

* More math improvements
* more math functions
* stack check
* added error message when trying to modify read-only table; fix gSmluaConstants printed to console
* 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
Some changes for gfx vtx duplication:
- Only vanilla (read-only) stuff is duplicated
- Stuff is duplicated only once, and uses a map rom->ram for next iterations
- Stuff is restored to original values on network shutdown
also fixes incorrect types in some extern declarations
* 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
This is to fix writing to read only memory, which would a crash if a mod tries to modify a display list from vanilla sm64.
it also makes sure that modifications to display lists are unique to the display list it was applied to
