yujiang wang 13265758ac Fix various issues related to lightmap 2-texel padding not being considered ...

* UVs in lightmap density view were shifting after building lighting. Fixed by considering the padding even if lightmap data is invalid
* Auto generated lightmap UV was snapping charts to the whole padded lightmap instead of the actual valid center region. Fixed by subtracing 2 texels from the packing resolution
* Also fixed some merging conflicts of auto gen
