The libprimis-headers file glexts.h defines a series of deprecated OpenGL bindings, such as GL_QUADS and GL_ALPHA, that have been deprecated as of OpenGL 3.0. Since libprimis only targets OpenGL 4.0 and higher, it would be a good idea to replace the code using these API features with equivalent modern ones.
