[cairo] scaled_font fini & directfb

[L A]

I am using cairo with the dfb backend. I have been having issues with
the DFB. It is running out of video memory. I found out that there are
unclaimed surfaces created by cairo scaled_fonts. It seems that
scaled_fonts are saved in a font map and are never freed (even when
scaled_font is gone). I understand the logic that they might be needed
in the future. But I simply dont have enough resources. Since I have
multiple cairo contexts in the system, I cannot call the
cairo_debug_reset_static_data function either.  What do I do?

Thanks
