add REGION_RECT

fix formatting

fix shader compile (region_rect after draw_data)

fix formatting

fix formatting

Review fix (move region_rect in main + remove useless visual shader options)

fix formatting

fix alphabetic order (+ remove useless action for spatial shaders)

typo + remove TYPE_LIGHT option for  region_rect
