These tests are covered by test_EnableThemeDialogTexture() in uxtheme/tests/system.c. These tests
are also misleading because a WM_ERASEBKGND message is needed to actually activate dialog theming.
Without the message, they give the impression that EnableThemeDialogTexture() does nothing and
DefDlgProcA/W() are not hooked.
