depth
This allows you to explicitly set the Z-Buffer depth. Most 
applications will work best when Disabled is selected

blending, visual artifacts can occur. This option allows 
you to select how the application should handle both 
features at the same time. In most cases Error 
Diffusion
 will handle this situation quite well, but there 
are a few cases where selecting Ordered may be 
necessary

feature
