to get M_PI from the platform headers and cast it to float.

in the scene where we can push and pop cameras.

that 2-year old "temporary Win32 hack".

currently works for images (SDL and GDI+ loaders) and sound samples.

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

BtPhysTest now implements it with the BtKineCC logic -just modify that now-.

Useage :
- Link action to key :
Input::LinkActionToKey(ACTION_TYPE Action, struct Key Button);
Input::UnlinkAction(ACTION_TYPE Action);
- Query action directly :
Input::GetStatus(ACTION_TYPE Action);
Input::WasPressed(ACTION_TYPE Action);
Input::WasReleased(ACTION_TYPE Action);

Also works with raw button, but not advised :
Input::GetStatus(Key Button);
Input::WasPressed(Key Button);
Input::WasReleased(Key Button);

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)

on Windows if using Visual Studio; if using MinGW, try to stick to the
original main() entry point.

do not open a console at startup.

Phys::Simulation is now an entity.
Phys::Simulation now implements timesteps correctly.

Added several delete/destructor, speeds up exit & saves memory.

Added lol::phys::Simulation, lol::phys::EasyPhysics for easy physic uses.
Added PhysicsObject, wich hold EasyMesh & EasyPhysics components so it is easy to use. Easy seems to be the consensus.
BtPhysTest now works with new physics classes.

Known problem for this commit:
Physics is not properly setup.
There might be memory leaks, I don't think I've parsed all new/delete.
A LOT of primitives are not taken into account.
