* Now using a Factory and Instance approach to simplify and beautify the code at the same time. * Additionally we now keep track of created filters and only load data if there is a filter active, and unload data if there are no more filters. This reduces memory and GPU overhead when no filter is active, but adds a first time filter creation overhead. * Variables and functions now use snake_case.
