yeah, the getprocaddress is entirely up to pyopengl. pygame also 
doesn't need to make a load_library call of any kind available.

but i wasn wondering if internally SDL_GL_LoadLibrary should be
called? from what i can see pyopengl doesn't support runtime loading
of a GL library. nevertheless, pyopengl can be compiled to be using
any opengl library out there (ie, mesa or whatever). i think it is
important the SDL's GL stuff is using the same GL library that
pyopengl is. 90% of the time the user will only have one default
opengl library on the system, and there won't be any trouble. but
in the case a user has multiple opengl libraries, it will be important
to call SDL_GL_LoadLibrary internally.

the question then is, can we determine which opengl library pyopengl
is linked to? i'm not sure if pyopengl has any support for this type
of functions, "which_gl_library()" heh?
