Is a set of rendering options for the
TGLShadowPlane property
shadowoptions. Includes options for stencilling and transparency. Includes the following set items:
spoUseStencil: plane area is stenciled, prevents shadowing objects to be visible on the sides of the mirror (stencil buffer must be active in the viewer too). It also allows shadows to be partial (blended).
spoScissor: plane area is 'scissored', this should improve rendering speed by limiting rendering operations and fill rate,may have adverse effects on old hardware in rare cases
spoTransparent: does not render the plane's material, may help improve performance if you're fill-rate limited, are using the stencil, and your hardware has optimized stencil-only writes
