debug draw fixes are really un-numerous in ze lol, it seems

......

Seems to still build in lol, will check other works to be sure

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.

- removed 0 CR characters
 - removed 7 trailing whitespaces
 - replaced 332 tabs with spaces

- Most recent version is in with index buffer support

Shader replacement code for older shader version is now fixed

This will allow us to generate sounds on the fly on several dedicated
channels. Until now we could only play fully loaded samples.

Input was broken, as well as palette generation, and even texture
upload. Should be all good now.

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 will help us deal with shader name collision. Breaks the Windows
build for the moment, unfortunately.

This allows actors to perform draw commands in TickDraw(), even
if it’s not exactly what we want in the future.
