Merged directional and point/spot lights into the same atlas again. Added two additional atlases to support 16 bpp VSM style shadow maps.
Added new dropdown to AdditionalLightData to select precision if available.
Added support for the new shadow library to fptl.
Introduced a new shadow include inline file to support different shadow setups for different light loops per project.
Restructured the code a bit in order to support multiple instances per project.
Fixed and issue with broken shaders when one of the samplers was set to 0.
