crop for vdmx

hello out there
i made a little qtz for cropping the screen.
since there is a little chrash problem with the vdmx crop and crop vv (witch mrRay already fixed in the next beta) i made one on my own.
its my first qtz for vdmx.
it works good if u put it in the media bin but i dont know why the top slider dosnt work right if u put it in the qtzefx folder.
if u got a solution for this please let me know.
