GPULightmapper: execute dilate before denoise

Browse source 
Dilate fills gaps that are caused by the rasterization. Previously denoise
was done before dilate which caused the gaps to become filled (non-zero). This
resulted that the gaps were not recognized by
dilate  and the background color leaked.

This is fixed by executing dilate before denoise.
