project: Fix License, License headers and Copyright information 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.

gfx/lut: Add a simple but efficient LUT producer and consumer For simple image and video editing, LUTs (Look-Up Tables) are vastly superior to running the entire editing operation on each pixel - especially if all the processing can be done inside a single shader. Due to the post-processing requirements for our LUTs, we are limited to 8 bits per channel - though clever use of the unused Alpha channel may result in additional space. For our purposes however, this is definitely enough.

project: Apply more C++ paradigms to the code - Use auto in places where code clarity is improved or identical. - Replace trivial constructors and destructors with default. - Use true random for random generation. - Use std::string_view where it is valid to do so. - Apply const where it is valid to do so. - Use references where it is valid to do so. - Manually optimize memory usage with std::move and std::copy. - Opt for memory efficient containers where the size is known ahead of time.
