Fixes several files incorrectly stated a different license from the actual project, as well as the copyright headers included in all files. This change has no effect on the licensing terms, it should clear up a bit of confusion by contributors. Plus the files get a bit smaller, and we have less duplicated information across the entire project.
Overall the project is GPLv2 if not built with Qt, and GPLv3 if it is built with Qt. There are no parts licensed under a different license, all have been adapted from other compatible licenses into GPLv2 or GPLv3.
This drastically improves stability and prevents all exceptions from leaking into libobs C code, which prevents crashes and unexpected freezes from exception handlers further down the stack.
Additionally minor work was done to further improve the quality and user experience for the filter.
Earlier versions tried using Trilinear as the Filter, but the correct name is Linear. With this the sampling is now set to be Linear instead of undetermined.
Additionally the logic for the displacement was adjusted and now no longer renders incorrectly when going from texel to texel. This was due to the unstable math being performed to retrieve the sign of the number, but the sign() command can do it without this math being required.
