rm attachmentCount shader flag; 

It doesn't work as intended (due to glslang issues?).  The current way
to write a shader that uses multiple attachments is to declare multiple
output variables, which is a little better because you can name them
however you want and customize the type.

It would be nice to be able to support a "void" entrypoint for multiple
attachments so you don't need to awkwardly return the first target's
color, but I can't find a way around this right now.
