This commit adds functions `glm_perspective_lh_no` and `glm_perspective_rh_no` to the code. Unit tests are added and this commit follows the new pattern of adding the a new file per coordinate-system and clip-space tuple. . Makefile.am updated . removed test/glm_cmp project stub . unit tests include naive implementations to as well as magic number ref-data generated by the corresponding GLM functions. No tests run yet on Windows or Mac.
