These weeks have been a little bit crazy for me(my bachelor thesis need to be wrote :) ). And a bug in my fill pattern code was make me crazy. Finally last week I fix it and implement some blend operations(CLEAR, SOURCE, IN, OUT, ATOP, XOR and others) and in parallel began to learn about font rendering.
I already have something working.
But it is a little bit ugly because it does not have antialiasing =/. So these weeks i have plans to improve the code and fix bugs, bug and bugs. After that work in font support and finally make some work with anti aliasing techniques. I already have studied some papers but if someone had others ones would be fine :).
