In this case you expect a screenGrabExist function that returns TRUE if
any of the listed plugins has a screen grab - at least that's what your
code does ;-) 
If you return TRUE if name != NULL this means you return TRUE if the
currently compared screen grab (in the loop) matches one of your listed
plugin names. 
otherScreenGrabExist is supposed to return TRUE if any _other_ plugin
than those listed has a screen grab.
