This lets us use the code for non-float variable types. I also got
rid of the mat4-to-quat code so that users are forced to use the
mat3-to-quat code and possibly discover places where their code is
suboptimal.

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.

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

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

scene so that g_scene can be deprecated later.

that lets us draw integer random values too.

- fixed 1270 CR characters
 - fixed 56 trailing spaces
 - fixed 5085 tabs

Added RayCastResult & a naïve integration for EasyCharacterController.
Enjoy !

Character integration better but still not working.

Small tweaks in the BtPhysTest demo.
Added Ghost Object skeleton (not tested)

to char *.

+ Constraint hollow class.

+ weird racist test : the primitives only collide with their same type.
