- Implemented a simple gif encoder based on the rust crate "gif". - Currently supported input pixel formats are RGB and RGBA - The encoder dynamically changes frame delays to approximate the actual input framerate - For the moment, each frame uses its own local colorpalette, leading to good image quality, but big files - Every frame is currently a full frame. No incremental frames for now - The produced GIF is currently compressed (LZW)
