[grits] Change GdkEventExpose to gpointer

[Andy Spencer <andys src gnome org>]

commit cca3466d1d77b5de277631d51b08753978d8f6b1

    Change GdkEventExpose to gpointer
    
    On GTK 2 this a GdkEvent, but in GTK 3 it's a cairo surface. Since we
    don't use the structure anyway we'll just call it a pointer.
