Is libswscale still required?

Compiled commit a7bf701c3d61dacde50c895d9449260d85bcbb08 , it does not link to libswscale.so.2 anymore:

$ objdump -p /usr/lib64/vdpau/libvdpau_va_gl.so.1|grep NEEDED|sort

I've removed libswscale in favor of GLSL-based conversions. But it turned out, GLSL-based code was not noticably faster than libswscale-based. On slower machines it can be even slower. For example on Atom N270 + GMA950 glsl gives about 30 fps on colorspace conversion only. Libswscale code performs at about 100 fps.

So I think I'll use libswscale again.
