// Simplified Bumped Specular shader. Differences from regular Bumped Specular one:
// - no Main Color nor Specular Color
// - specular lighting directions are approximated per vertex
// - writes zero to alpha channel
// - Normalmap uses Tiling/Offset of the Base texture
// - no Deferred Lighting support
// - no Lightmap support
// - supports ONLY 1 directional light. Other lights are completely ignored.
