39     incoming value and action taken based on that value. The stencil buffer is
40     updated during rasterization, and the operation used to update the stencil
41     buffer is chosen based on whether the fragment passes the stencil test,

113     or pass. sfail indicates what action is taken if the stencil test fails.
114     The inputs to the stencil operation are the stencil reference value, the
115     stencil operation source value, and the current content of the stencil

144         The stencil operation source value is set by calling StencilOpValueAMD
146     to the new value of the stencil operation source value.

157     functions are both ALWAYS, the front and back stencil mask are both set to

220     1) Is the stencil mask applied to the stencil operation value?
223     The stencil operation is carried out on the full value. The stencil write
224     mask is applied to the result during stencil buffer update, however.
230     to be generalized add and subtract operations. However, the stencil
232     1. Therefore, in the default state (assuming the stencil operation source
235     3) What if I want to apply a logical operation with the stencil reference
236     value and the current stencil buffer contents?
238     RESOLVED: Set the stencil operation source value to the same thing as the
239     stencil reference value.
