Many illustration techniques such as transparency need to have correctly sorted graphical primitives. As this is too costly to perfrom for every rendering cylce, it should not be done always. In order to achieve nice images, however, it is quiet important. So, with this ticket a mechanism will be built, that allows to sort all primitives for a single rendering cycle to produce a nice image until the next redraw.
We need to consider several ways of doing this:
- sort primitives
- depth peeling
- stochastic transparency approach
