textureLodOffset — perform a texture lookup with explicit level-of-detail and offset

gsampler2D sampler, |
| vec2 P, | |
| float lod, | |
ivec2 offset); |
gvec4 textureLodOffset(

ivec3 offset); |

ivec2 offset); |

sampler
Specifies the sampler to which the texture from which texels will be retrieved is bound.
P
Specifies the texture coordinates at which the texture will be sampled.
lod
Specifies the explicit level-of-detail from which texels will be fetched.
offset
Specifies the offset that will be applied to P before texels are fetched.
textureLodOffset performs a texture lookup at coordinate P from the
texture bound to sampler with an explicit level-of-detail as specified in lod.
Behavior is the same as in textureLod except that before
sampling, offset is added to P.
