The GTK and OS X platforms already ignored the requested bit depth and
always used 32 bit. Windows and SDL would set a 16 bit color depth for
the screen, but still did all of the rendering short of the final
present in 32 bit.
The magic value -1 is used to denote "current screen mode", but it has trouble fitting into the unsigned concept. An alternative would be to use 0 as the magic value, but that would include quite a few places (including existing configuration settings) to change.
As discussed in http://forum.openclonk.org/topic_show.pl?tid=2917, I
have merged all copyright notices into a single file and referenced that
merged file from each source file.
For the updated source files, the timeline has been split into three
parts:
1. Pre-RWD code (before 2001)
2. RWD code (2001 through 2009)
3. OpenClonk code (2009 and later)
All pre-RWD copyright notices have been left intact, as have RWD-era
copyright notices where the file did not have a RedWolf design copyright
notice but only individual author ones. All copyright notices of the
OpenClonk era have been replaced by a single notice ranging from the
first recorded year to the current year (2013). Mape code did not get a
OpenClonk Team copyright notice because it is somewhat separate from the
main OpenClonk codebase and has only been touched by Armin Burgmeier.
The windows code now has to delegate to StdD3D like it does for the
resolution setting, but for the other ports the code fits much better in
the app source files.
