Added macros to help basic setup

getter default params are better now

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

- Most recent version is in with index buffer support

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

We already have the convenient degrees() and radians() functions to convert
between angle formats. This commit involves a lot of refactoring here and
there and I may have missed some places where conversions were needed. But
hopefully there aren’t may such places.

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.

Scene rendering logic is now better

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

MeshViewer first pass

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

- removed 1210 CR characters
 - removed 17 trailing whitespaces
 - replaced 0 tabs with spaces
 - fixed 5 svn:eol-style properties

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

Big FAT pass on windows-warning. It is better now.

and 2) fuck the Visual Studio compiler that crashes when confused.

MASK to SWIZZLE in the vector templates, rename matrix<> to mat<> for
consistency, implement transposition for all matrix sizes, make matrix
columns private and only accessible through operator[].

Implemented Safe-Enum for everyone.
Now the power is in the Safe-Enum for all.

Added workbench, for personnal experimentation.
