E3View_State_SetShaderSurface is not a public method... and in the =20
case we need to pubblish the whole set...
Anyway is not a problem now since I've decided for including =20
everything and control it with properties

this is not a problem if you're willing to duplicate the code in =20
every plug-in

my problem is that I want to have several hidden-line renderers in my =20=

app (other than the 'classics' renderers Wireframe-interactive-OpenGL-=20=

Cartoon, that are not in discussion)

but in the current state I've to compile them inside the Quesa Lib... =20=

leading to too many renderers in the default installation..

So I'll made a single hidden-line, controlled by a bunch of properties,
Also with the rayshade I want to pubblish a number of properties =20
(gamma correction and antialias level, and antialias method are the =20
first three)
