// 
// Collision 'Types'
//
// This enum defines the collision type bit-field that is used in render object 
// collision detection.
//
// The collision type field in a collision or intersection test is used as a 
// low-level collision mask.  It will be 'AND'ed with the collision type of 
// the render object and will ignore the object unless the result is
// non-zero.  In Commando, we use this to implement separate collision 
// representations for "physical" collisions versus "projectile" 
// collisions.  I.e. we use a very simple mesh for the character's 
// physical collision and a more complex set of meshes for checking whether 
// a bullet hits a person.  This masking system is not meant to be a general 
// "collision grouping" system.  You should use a higher level system for doing
// things like making bullets ignore each other, etc.
//
// One more wrinkle to the system:  The collision type in the render obj
// will always have the LSB set (COLLISION_TYPE_ALL) so that you can always
// do queries against every piece of geometry in a render obj if desired.
