Unfortunately, easymesh code still relies heavily on its specifics, so I’m
letting it live as lol::easy_array for the near future. But it’s going away.

This is the first step to getting rid of lol::array in favour of std::vector.

return 1 added after sam remark

Added macros to help basic setup

getter default params are better now

Next pass is clean-up and fix of all the old usage

Will resume on other computer.

We have no hope of extending lua_State to add more data to it, because
that object may be created by Lua itself, for instance within a coroutine,
and it has no knowledge of our version of the object.

This has proved unreliable because coroutines create whole new environments,
so one of the only ways to store user data and access it even from coroutines
is to use lua_setglobal().

This doesn’t work properly yet because PICO-8 uses a few language
extensions; we will have to decide whether to modify the Lua
interpreter, or change the code on the fly, or something entirely
different.

Using “Array” instead of “array” is now fully deprecated, and I replaced
the Log::Debug() etc. functions with msg::debug() etc. because log:: was
unavailable due to being a maths function.

Added up-to-date copyright notice and BOM to modified files, just in case.

The containers no longer force the user to use the ptrdiff_t type for
size information. For convenience, size() now always returns an int,
and the size_s() method offers a way to handle arrays with more than
2 billion elements. Internally, we still use ptrdiff_t, though.

Since so much code had to be changed, I took the opportunity to get
rid of capitalised accessors for classes that are lowercase.

Lua only supports the "double" type for now, so storing a 64-bit integer
would lose information unless it's encapsulated in a more complex type.
I prefer to disable these accessors for now.

Reworked Primitive logic for scene rendering
FileUpdateTester works now .....

MeshViewer first pass

Added Texture (by image) update in TextureImage (and tileset)
Added lolimgui first integration pass

Added InputProfile in Controller
Added ExecLuaCode

Add SafeEnum var in lua
MeshViewer SceneSetup is operational
Added imGui to vs-solution, not implemented yet

First pass on EzMesh integration (doesn't work yet)
