Provide projection matrices implementation for both left-handed and right-handed coordinate systems. about glm

Upvote from me!

I use 'left handed' OpenGL so I'm having to 'roll my own' frustum/ortho etc functions.

Are those the only function you had to add?

Pull request are always welcome! :D

I was kind of doing them as I needed them, so there're probably more...

Pull request are always welcome! :D

I can have a go, but how would you like to handle left handedness?

Via a #define, like GLM_LEFT_HANDED? Or via more functions? Perhaps both...?

frustum_lh( blah ){...}

frustum_rh( blah ){...}

frustum( blah ){
#if GLM_LEFT_HANDED
frustum_lh(...);
#else
frustum_rh(...);
#endif
}

Or maybe even another parameter to frustum( ...,bool lh )?

I think both with a define to select the user default approach for glm::frustum is the right way to go with this.

Thanks for contributing!

Since GLM_LEFT_HANDED is now a thing, can this be closed?
