RE: [Plib-devel] Texture and blend modes

[Ben W. <be...@bg...>]

One more thing, I you may now this but I thought I would say it anyway. When
you pop it of the stack, it purmanatly pops off. 
A on stack
push
B on stack

pop // b comes off leaving just a.

Ben,

I just added glGetError() calls after each push/pop.  These always
return zero (even the very first call) and their presence makes the
rendering work ...

Now I take out the calls to glGetError() and it still works ... lovely ...
:-(

But I duplicate the code else where and it obviously isn't restoring
the depth_test ... :-(

Thrust back into opengl la-la-land ... I might be better off just
putting things back to the way that I know they work and saving myself
about 100 or so hours ...

Curt.
