plus these are easier to type.
i do not anticipate needing structured color types for any other
type of components (e.g. i don't see a need for an ARGBu16x4, etc).
so i am fine with just having `ARGB` being associated with four u8's
with no real indication of this in the type name itself.
mostly working, but the imgui ui part is only a placeholder.
also this example project is kind of overly complicated, but i really
wanted this to be something that somewhat resembles a real tool that
i'd want to build.
