EnvironmentMapEffect supports cubic environment maps only with an optional Fresnel effect.
Here I've added support for both spherical environment maps and dual-paraboloid environment maps.
The spherical and dual-paraboloid implementations support the same Fresnel effect controls.
To keep the number of shader permutations down, I only implement per-pixel-lighting for these two new map types.
For simplicity, dual-paraboloid environment maps are 2D texture arrays with 2 entries.
Also converted the bool parameters for NormalMapEffect, EnvironmentMapEffect, and PBREffect into EffectFlags.
