[PATCH 0/3] MR9490: comctl32/toolbar: Erase the background in TOOLBAR_Refresh() when...

[Zhiyi Zhang (＠zhiyi)]

comctl32/toolbar: Erase the background in TOOLBAR_Refresh() when TBSTYLE_TRANSPARENT is present for comctl32 v6.

Comctl32 v6 erases the background when TBSTYLE_TRANSPARENT is present when handling WM_PAINT, not
when handling WM_ERASEBKGND. WxWidgets relies on this behavior to draw the toolbar background.
Please see https://github.com/wxWidgets/wxWidgets/blob/v2.9.4/src/msw/toolbar.cpp#L1805.

Fix tlReader 10.1.0.2004 toolbar broken rendering after 5e70fef5. After the commit, the comctl32 v6
version is properly reported and wxWidgets decides to use a comctl32 v6 specific code path.
