textureProjLod performs a texture lookup with projection from an explicitly specified level-of-detail.
       The texture coordinates consumed from P, not including the last component of P, are divided by the last
       component of P. The resulting 3rd component of P in the shadow forms is used as Dref. After these values
       are computed, the texture lookup proceeds as in textureLod(), with lod used to specify the
       level-of-detail from which the texture will be sampled.

sampler
           Specifies the sampler to which the texture from which texels will be retrieved is bound.

       P
           Specifies the texture coordinates at which texture will be sampled.

       lod
           Specifies the explicit level-of-detail from which to fetch texels.
