The new C1Icon is a set of classes which generate monochromatic icons that can be tinted and resized easily, without all the pain points that bitmap-based icons have. These icons are used internally in some controls, such as the new Ribbon for WinForms, where users are able to specify different icons through the API. C1Icon sources can be fonts, vectors (path or SVG), and images. C1Icon is supported in WinForms, WPF and UWP.
