- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg). - Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Fixed handling DVB subtitle fill region codes for 2 and 8 bpp. - Fixed displaying DVB subtitles (thanks to Rolf Ahrenberg for helping to debug and
understand subtitle page refreshes):
+ Fixed handling DVB subtitle fill region codes for 2 and 8 bpp.
+ Fixed handling pages without an explicit END_OF_DISPLAY_SET_SEGMENT.
The FINISHPAGE_HACK is no longer necessary.
+ Fixed handling "page refreshes".
+ Added DebugBitmaps, which, if set to true, generates an HTML page with a sequence
of images, showing the subtitle data as it is processed.
+ The debug output now uses some indentation for better structuring.
+ Fixed handling subtitles encoded as a string of characters (the very first
character was always skipped).
