Theory:
----------
because PresentWindowsEffect::screenCountChanged() is shortcut
for "if (!isActive())", but the desktopgrid doesn't call
PresentWindowsEffect::setActive (or at least
PresentWindowsEffect::screenCountChanged), so the effect can
"miss" the increasing screen count change (it sees the signal,
but ignores it) and when desktopgrid calls it, it assumes the
m_gridSizes array is big enough (but it isn't)
Steps:
----------
1. effects are loaded, 1 screen present
2. 2nd screen gets added, but inactive effects ignore that
3. desktop grid gets activated, updates according to screen count,
calls presentwindows for screen #2
4. presentwindows data is only prepared for one screen from step 1
=> BOOM

grid, if this code is not to be used by KDE 4.3 it should be removed and
added to a test effect instead.

Prefix all the #ifndef #define ... #endif symbols with KWIN_ , just in case
somebody uses CLIENT_H or so too.
And don't include config.h .
