+ Bloom effect + PixelInformation + Many Summaries + Add-methods for CVectors + Exposure-Field in GenericCamera for HDR. ~ ColorAttachments now can have PixelInformation ~ Transformed MeshAttributes to a own class ~ Fixed the non-applying of transformations at texts ~ Added more information to the context ~ Improved Pipeline-Process. ~ Changed how Uniform takes arrays - Light system
