Log:
[CONSRV][WIN32K]
- Fix console palette setting; introduce the ConsoleMakePalettePublic control code for
NtUserConsoleControl API which
is called by the SetConsolePalette to make the given palette handle public (indeed, the
caller to SetConsoleHandle
gives to this API a GDI palette handle which is aimed at being used by another process,
i.e. by CSRSS.EXE; in normal
operation this is impossible unless saying to GDI that the handle is meant to be public;
that's what it's done there).
Thanks to Aleksander and David (who provided tests) and Timo (see revision 60725) for
having helped me in understanding
what happened exactly there.
- Remove now-unneeded DPRINT1s and the hacked palette that was introduced in revision
60629/60641.
