-// NOTE: If stereo is enabled using Misc::StereoView::shaderStereoDefines, version 330 compatibility (or greater) will be set.

-// NOTE: If stereo is enabled using Misc::StereoView::shaderStereoDefines, version 330 compatibility (or greater) will be set.
-
-// USAGE:
-// To create a stereo-aware vertex shader, use the matrix accessor functions defined in this .glsl file to compute gl_Position.
-// For the vertex stage, usually only gl_Position needs to be computed with stereo awareness, while other variables such as viewPos 
-// should be computed in the center camera's view space and take no stereo awareness.

-// A typical gl_Position line will look like the following:
-//    gl_Position = mw_stereoAwareProjectionMatrix() * (mw_stereoAwareModelViewMatrix() * gl_Vertex);
-//
-// If you need to perform intermediate computations before determining the final values of gl_Position and viewPos,
-// your code might look more like the following:
