ok, got it :) i crufted few pieces of code so now I have hardcoded 
yellow subtitles in YV12. Just to attract some flam^H^H^H^Hcomments, 
here is a patch (rather a sketch of one). Packed formats should be easy 
as they won't involve additional changes in the code outside of osd.

In addition to three source pointers & strides there are args specifying 
x0 mod 2 & y0 mod 2 which I needed for proper chroma/luma alignment.
