I loaded the functions using Load_GL_VERSION_3_3 (and similar) from the Free
Pascal RTL and it seems to correctly load the functions.
Right now I’m using 2.1 and the fixed pipeline because I don’t really need
shaders but I’m learning shaders and matrix transforms now so if there’s any
performance benefit I can update my code base.
