render callback implemented
prepared clone function
rendercallback works so far, must only find a way not to assign in that case
the logo is now an own project hgl file
simple types get generated completely automatically, contd.
* added interpreter option to enable render callback * fixed memory leak
callback procedure done, but expressionparam in debugprocedure must get evaluated
callback implemented, but it dumps instead of printing
better to use help of debugger, since it is is quite old code
