Set baseline as "baselineConstrained" for Stage3D

[aglitchman]

Since FP 11.4 stage3d.requestContext3D() has second parameter: baseline. Setting baseline as "baselineConstrained" by default will significantly increase amount of supported GPUs:

You should implement it by this way:

Bump.

There's some important limits on shaders so I'm not sure h3d per-pixel lighthing model would work with it atm.
The stage3d specifics has been moved to the driver. I might add a static var there to force the baseline parameter.

h3d is primarily a 3d library, to have good performance hardware skinning is mandatory so I agree with Nicolas.

I'll close for now, feel free to provide patch if need be :)
