Effects/model-combined.eff fix techniques numbering. Make active under rembrandt too. add model-combined-deferred as a stub for now for specific
Rembrandt use.
Users of model-combined with normalmaps should change the technique number to 9, and duplicate that entry for technique 8.
Fix some longstanding png warnings. Provide null_reflectdir.png for model-combined
This should fix part of bug #726

Add a technique that initialize the buffers of the Rembrandt renderer
(use Multi Render Target)
Renumber techniques that depends on old technique 10 (now 11) of model-default
The overriding of the color mode uniform in the default model effect
wasn't working. It's difficult to override the individual properties
of techniques, especially if their names aren't unique. So, I changed
the model-default effect to use a parameter for the color-mode
uniform; material-off.eff and material-diffuse.eff override that.
Use two-pass rendering for some shaders to reduce the cost of expensive shaders.
Implement some material animations using a shader uniform.
Eliminate use of gl_FrontFacing. It's too buggy on ATI/ Macintosh.
