Message : Move index range calculations into VertexArray. This is in preparation for removing the entire DrawCallParams struct. This struct was big enough to cause a performance hit on draw call perf tests just by virtue of initializing the fields. Also dereferencing the struct members is slower than reading function parameters since it adds an indirection. Also includes some error refactoring to enable moving code to a shared location. In total this patch series reduces overhead by up to 5%.
