This test hangs forever for me under XP displaying a listbox with "ENTRY xx"
entries if winetest_debug != 0. Once I forcibly set winetest_debug = 0 the
test never produces test statistics (failed, skipped). The whole idea of
playing with winetest_debug and DRAW_CHECK inside of the drawing test looks
broken to me.
