Stencil_func

Description
Tests the behavior of NV097_SET_STENCIL_FUNC (0x00000364).
Each test renders a series of red quads unconditionally, then renders an invisible quad on top to set the value of the stencil buffer to various test values. Finally, a green quad is rendered across all test patches using the selected stencil function, causing areas that pass the function to turn green, while failing pixels remain red.
