This is a shameless, self-promoting post.
I traced the Sarawak flag to a vector format - SVG. It can be found here. And for the inevitable question: why SVG? It can be resized to any size, without loss in detail; it's an Open Standard and XML; and most importantly, it's quite compatible with most browsers and vector-editing software.
Other modifications that are on Wikipedia are a map of Malaysian states and yet the same map with Kuching marked.
Yes Mr. You-know-who-you-are, you may talk about this with me but not reveal it to anyone else.
