The Transform filter will now no longer render the child source more than once per tick(), resulting in an overall speed up for heavy sources. This also applies to mipmapping and shape rendering. Any other calls to video_render will instead just use the cached texture. Additionally the crash on exit has been fixed which was caused by strings.hpp containing static const char*s and using these directly in obs calls. Instead we now use #define for those property names
