[KDE on Mac OS] KWindowSystem::numberOfViewports and related

[younker]

Hi,

What does the following functions do?
int KWindowSystem::numberOfViewports(int desktop)
int KWindowSystem::currentViewport(int desktop)
void KWindowSystem::setCurrentDesktopViewport( int desktop, QPoint
viewport )

These functions are defined in KWindowSystem in kwindowsystem_mac.cpp
and kwindowsystem_win.cpp,
but these functions are not declared in kwindowsystem.h, so when
compiled it on Mac OS, will cause
a compiler error, these functions is not defined in kwindowsystem_x11.cpp.

Regards.
