[PD] 3 1/2 shaders help!

[vade]

if that is the issue, then it should (?) work for sampler2D and  
texture2D, but I thought we had tested that the other night at the  
Patching Circle and found it to not work?

ill write a simple shader shortly using square textures as inputs and  
we can test the theory out.
