As long as you use -noslices, draw_slice will not actually be used.

Of course not. I am not aware of any YUV being supported. You will have
to write pixel shaders to do the conversion, which is why supporting
GeForce 3 may not be possible (I am not completely sure what exactly they
support with D3D).

It is quite straight-forward, in draw_osd you call vo_draw_text and
there you can specify the display size for which you want the OSD
rendered.
You may have to set force_load_font to 1 on when the display size is
changed to make the font size change though.
