I have been working on a similar project. Closest thing I could find are in the following links, but I doubt you will find a library with all the features you desire. These will only setup basic drawing functions, but it's a start. There are also some useful tools for bitmap converting and font creators if you dig around.

Almost everything else I have seen here is way overkill for what the poster seems to be asking for.
