Passing parameters from caller to subtitle renderer was done by temporarily setting certain members in the osd_state struct (which for all practical purposes are as good as global variables). This was the only purpose of these members. Rather than using such a messy way to pass parameter, put these into a struct sub_render_params. The struct was already introduced in earlier commits, and this commit just removes the parameter passing hack.
