glStencilMask - control the writing of individual bits in the stencil planes
void glStencilMask( GLuint mask )
mask Specifies a bit mask to enable and disable writing of individual bits in the stencil planes. Initially, the mask is all ones.
glStencilMask controls the writing of individual bits in the stencil planes. The least significant n bits of mask, where n is the number of bits in the stencil buffer, specify a mask. Wherever a one appears in the mask, the corresponding bit in the stencil buffer is made writable. Where a zero appears, the bit is write-protected. Initially, all bits are enabled for writing.
GL_INVALID_OPERATION is generated if glStencilMask is executed between the execution of glBegin and the corresponding execution of glEnd.
