[PATCH 0/1] MR1112: comctl32/tests: Use a toolbar with TBSTYLE_FLAT in toolbar visual tests.

[Zhiyi Zhang (＠zhiyi)]

Fix a test failure when theming is off. A toolbar without TBSTYLE_FLAT will fill its checked button
background rectangle when theming is inactive, overwriting the checked pattern required for the test.
