0e84c54306 Added shader parameter register count information in the D3D shader file format.

Removed the ElapsedTime shader parameter, as wrapping it is problematic depending on the calculations it would be used for.
Removed support for bool & int shader parameters from Graphics, as bool constants are not supported in OpenGL 2.0, and int parameters are not (at least currently) needed, and can lead to worse performance.

Do not render light to stencil if camera is inside the light volume.
Added optimization for directional light shadow casters that are fully occluded by another shadow caster: do not render the lit pass for them.
Removed the alpha masking hint. Alpha test no longer gives the batch a lower priority.
