Adding two filters of the same type on one source results in OBS freezing

[an40us]

To reproduce this issue add two dropshadow filters on any source.

Also, this issue persists in this case too: if you try to add filter to the scene, that contains a source with a filter of the same type, OBS freezes.

I also tried to investigate myself - creating an empty script, that only defines a filter source doesn't cause this issue. After adding some code to video_render function i was able to reproduce the issue. Furthermore, removing the code from dropshadow's video_render still produced the same issue.

I already saw this myself but sadly I don't know how to fix this issue yet. I think it has something to do with how they implemented the Lua feature because I think I remember I was able to add the same filter multiple times when the filters were still in C.

I see. If I find a way to make this work, I'll commit the changes.
