According to:

http://developer.apple.com/documentation/GraphicsImaging/Reference/AGL_OpenGL/Reference/reference.html

it should be AGLPixelFormat (without the "ID" suffix).

And that's exactly what togl.c uses.

Also, I note that aglCreateAGLPixmap isn't mentioned on that page. 
However, it does describe aglCreatePBuffer, which is probably the
appropriate function to use (similarly, the X11 implementation should
probably use pBuffers if they are available).
