- Fixed the Language header of the Serbian translation file (thanks to Ville Skyttä).
- Added anti-aliasing when upscaling bitmaps (improves the display of SD subtitles
when replayed on an HD OSD).
- Renamed cBitmap::Scale() to Scaled(), because it doesn't modify the bitmap itself,
but rather returns a scaled copy.
