Improvements to spudec (DVD/VobSub) subtitle code:

 - runtime selectable positioning, like with text subs
 - runtime selectable scaling/antialiasing algorithm
 - gaussian blur scaler (finally dvd/vobsub doesn't look like shit!)

+Antialiasing/scaling mode for DVD/VobSub. A value of 16 may be added
+to mode in order to force scaling even when original and scaled frame
+size already match, for example to smooth subtitles with the gaussian
+blur. The available modes are:
