* Clear color values are not explicitely sent to the rendering backend as-is. Previously, converting from Color32 to Rgba caused an srgb->linear conversion. This conversion is incorrect if the backbuffer doesn't perform automatic conversion from linear->srgb (lack of this conversion is generally what egui assumes!). * fill in pr numbers in changelog * Epi comment fix Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com> * Color32 comment fix Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com> * move changelog line * rename fix * use backticks in doc --------- Co-authored-by: Emil Ernerfeldt <emil.ernerfeldt@gmail.com>
