GCBITSSTENCIL
stencil size.
GCBITSACBUF accumulation buffer size.
GCMSSAMPLES number of samples in the multisample buffer.
GCBITSMSZBUFFER
multisample zbuffer size.
GCMSZMIN minimum depth value that can be stored in the multisample
z-buffer.

DESCRIPTION
getgconfig returns the size of a buffer or a state of some buffers in the
current buffer configuration in the current drawmode. GCBITSZBUFFER,
GCBITSACBUF, and GCBITSMSZBUFFER will return a negative size if the
buffer is signed.
