Brilliant Highlights 2h473h

Description
This is a modified shader for Doom 3 and RoE (and Quake 4 as a separate mod) which enhances the appearance of lights and bumpmaps.

-------------
Features:
-------------

# HQ specular highlights #
- Power function based falloff
- Dynamic falloff (shinyness)
- Specular map masking
- Reflect vector math for true per-pixel result

# HQ Normalmapping #
- Normalmap normalization increases bumpmap quality
- [b](new)[/b] Normalmap filtering reduces specular aliasing

# HQ diffuse falloff #
- [b](new)[/b] New math based diffuse falloff enhances the contrast and appearance of lighting

# Backlights #
- [b](new)[/b] New backlights add realism by casting subtle light behind objects, as in reality, light tends to reflect and shine back from surfaces it hits.

Remarks:
--------------

- The unpleasant \"X-ray\" light has been fixed (from version 0.50)
- There seems to be a major incompatibility with the ATI Radeon X1000 series! Sorry guys, but this one I think is up to ATI to fix.. Older models should work fine.
- Performance trend has been downward from the first version of BH, and 0.60 is no exception :) Still way playable on my 6800GT @ 1280x720 4xAA 8xAF
