title: GLM: function taking degrees as a parameter is deprecated (WHEN USING RADIANS)
body: <p>Currently using VC++ 11 with SDL2, GLM, and GLEW. The issue is stemming from GLM when I attempt to do two things: Create a rotation matrix, create a perspective camera matrix (3D). </p>
  
  <p>The error is: <strong>"GLM: perspective function taking degrees as a parameter is deprecated"</strong>
   despite the fact that I am passing radians (as floats) to both functions. It says I should define something like "#define GLM_FORCE_RADIANS." Is that really necessary? </p>
  
  <p>Personally I use degrees for everything, but OpenGL, so having to convert back and forth (for AI movement and what not) is a pain and actually causes a spike in CPU when I have many NPCs moving.</p>
