kwin/effects/minimizeanimation.cpp
Rivo Laks 041673bf86 Effect's name in KWIN_EFFECT*() macros must now match effect's internal name in .desktop file,
without kwin4_effect_ prefix, so change the name in those macros to lowercase.
Some modifications to the macros themselves as well.

Effect loading via dcop might work again now.
