32d1c96dc0 Include affine.h in quat.h; remove needless decls 
* affine.h is needed for glm_translate_make
* Remove function declarations
  - glm_mat4_mulv since mat4.h is already included
  - glm_mul_rot as affine-mat.h is already include
  - glm_translate as affine.h is included with this change

d6b93f052e Add nlerp for quaternions 
Normalized linear interpolation for quaterions are a cheaper
alternative to slerp.  This PR adds nlerp operaiton for quaternions.

4639f3184a glm_lerpc(), glm_step(), glm_smoothstep(), glm_smoothinterp() (#98) 
* lerp, step, smoothstep

* glm_lerp() and friends are no longer clamped, use glm_lerpc() and friends
* mix() function as wrapper of lerp()
* no there are clamp and raw version of lerp functions
