testcase

Hi all,

I tired to enable visual style[1] for dialog in shell32.dll and comdlg32.dll.
Normally, a dialog will be themed by visual style when comctl32.dll v6 and
InitCommonControls() was used.
I implemented a dialog in a dll, and used 'Activation Contexts'[2] to let the
dll depend on comctl32.dll and call InitCommonControls(), but when the dialog
was called by another program, the dialog didn't be themed.

testcase.tar.gz is testcase I wrote for reproducing this bug.
You can reproduce the bug follow:
1. Install and enable a visual style theme in winecfg;
2. Download the testcase, unarchive it and make;
3. $ wine main.exe, click the 'OK' button. You can see button in the main
windows was themed but two buttons in the dialog was not themed. (as picture
testcase_wine.png showing)

Expected result:
The dialog also is themed, as picture testcase_windows.png showing.
