multipass shader

[andreasMank]

what's about mulitpass shaders .. rendering in textures and in pbuffer ???

I think there will be an GLSL update, where MRTs will be included. So multipass shader should be no problem.
Render to Texture will be covered soon by new extensions (Superbuffer or EXT_render_target).
