Driver stencil capability flags.

#define Value Description
D3DSTENCILCAPS_KEEP 0x00000001L Do not update the entry in the stencil buffer. This is the default value.
D3DSTENCILCAPS_ZERO 0x00000002L Set the stencil-buffer entry to 0.
D3DSTENCILCAPS_REPLACE 0x00000004L Replace the stencil-buffer entry with reference value.
D3DSTENCILCAPS_INCRSAT 0x00000008L Increment the stencil-buffer entry, clamping to the maximum value.
D3DSTENCILCAPS_DECRSAT 0x00000010L Decrement the stencil-buffer entry, clamping to zero.
D3DSTENCILCAPS_INVERT 0x00000020L Invert the bits in the stencil-buffer entry.
D3DSTENCILCAPS_INCR 0x00000040L Increment the stencil-buffer entry, wrapping to zero if the new value exceeds the maximum value.
D3DSTENCILCAPS_DECR 0x00000080L Decrement the stencil-buffer entry, wrapping to the maximum value if the new value is less than zero.
D3DSTENCILCAPS_TWOSIDED 0x00000100L The device supports two-sided stencil.


Stencil-buffer entries are integer values ranging from 0 through 2ⁿ - 1, where n is the bit depth of the stencil buffer.

These constants are used by the StencilCaps member of D3DCAPS9.
