Colour vision modes (Protan, Deutan, Tritan) in Preferences > Graphics, with palettes, shader and icon colours adapted per mode, translations and tests.
render.settings.set saves validated named render setups (camera, output size, exposure, environment) as one undo step, and render.settings.get reads them back without applying a camera. When validated render settings are the only change, the engine keeps the evaluated model instead of rebuilding it. Setups are saved under design format 21; format-20 designs read as having none. Fixes#658; refs #620.
