767c29cc2f dvbsuboverlay: use GST_LOG etc. for logging 
The dvbsub routines were originally designed as a mini lib with a
log callback (which from the looks of it in our case would always
be called and always assemble the string even with debug output
disabled). Some of these debug statements can probably be removed
or cleaned up some more.

implicitly defined to 720x576. The subtitle window information also present in
the display definition segment is not yet used.

a203ad1aab dvbsuboverlay: Fix more of the blending, so it looks quite good now 
* libdvbsub gives us alpha channel already, not transparency level, so
don't do another "alpha = 255 - alpha", this is done by libdvbsub.
* Fix alpha channel handling in interpolation - assrender had an additional
1bpp alpha bitmap as a possible mask, we don't. So don't use the palette
index array as alpha values; bug from quick code porting long ago to
changing pixel colors (assrender has a single pixel color for whole
regions or something, unlike dvbsub, which has indexed colors).
* Don't forget to reassign our YUV and other local pixel color variables
after shifting to work on the bottom part of a 2x2 subsample block, or
it's obviously very blocky.

Remaining issues in blending:

* Should probably be interpolating or doing something else useful with the
resulting U and V channels, so that most of the source pixel UV values would
actually be actually cared about, except for just one out of possibly four.

* Don't convert AYUV to ARGB in libdvbsub, and then back from ARGB to AYUV in
dvbsuboverlay for no reason

* Re-factor the whole thing to something more like textoverlay blending
* Related to that, perhaps cache the current spu in a good format for quick
blending on each frame, after which the more often called blending parts
might become more straightforward

efa1e9a1fe dvbsuboverlay: Fix blending bug regarding color channel addressing.

21abf9c4a8 dvbsuboverlay: Do blending calls when appropriate 
This gives us actually shown subtitles, however with bugs in the
current blitting code, resulting in very transparent subtitles.

84b52f6eb4 dvbsuboverlay: Implement fallback page_time_out honoring 
The spec has a page_time_out in the page composition segment to ensure
subtitles don't get stuck on screen for too much longer than intended,
when future page composition segments get lost on bad reception, or other
problems. Honor it in the gst plugin side.
