- The macro MaxFileName is now obsolete and may be removed in future versions. Use
NAME_MAX directly instead.
- There is no more fixed limit to the maximum number of cPixmap objects an OSD can
create. However, a particular device may still be unable to create an arbitrary
number of pixmaps, due to limited resources. So it's always a good idea to use
as few pixmaps as possible.
