spudec.c: crop subs, set scaled flag

Crop subtitle images produced by spudec.c: instead of returning a frame-
sized bitmap (with possibly large transparent regions), return a cropped
down rectangle of the visible part only. The old spudec scaler code had
this as spudec_cut_image(), but it worked on the data converted to the
old OSD format only.

Move most code to setup the sub-bitmap from spudec_get_indexed() to
spudec_process_data(), so that cropping can be done every time a new
subtitle is decoded, instead of every frame.

Set the sub_bitmaps->scaled flag. Without it, vo_gl and vo_vdpau
produced ugly artifacts on the borders.
