b0ce390d50 dvdspu: render to AYUV overlay
Instead of only supporting writing SPU data directly to YUV frames,
render the SPU data to an intermediate AYUV overlay buffer. The overlay
data is then blended to the video frame.

For the PGS format, the overlay buffer size is set to the size of the
Composition Window, and its position in the overlay composition is set
to the window position. The objects to render are now cropped when the
cropping flag is set.

For the Vobsub format, the overlay buffer size is set to the size of the
Display Area.

Once rendered, the overlay composition rectangle is now moved and scaled
to fit the video output size, to avoid clipping.
