- Fixed leading/trailing/multiple blanks in the translation files.
- Bumped all version numbers to 2.2.0.
- Official release.
2015-03-08: Version 2.3.1
- The new function cOsd::MaxPixmapSize() can be called to determine the maximum size
a cPixmap may have on the current OSD. The 'osddemo' example has been modified
accordingly. Plugin authors may want to use this function in case they use pixmaps
that are larger than the full OSD size. The default implementation sets this limit
to 2048x2048 pixel.
