[windows] Convert usages of GetDC to HWndDC Part 2.
https://bugs.webkit.org/show_bug.cgi?id=76750 Reviewed by Adam Roben. Source/WebKit/win: * FullscreenVideoController.cpp: (createCompatibleDCForWindow): Moved out the code which creates a DC for a window to keep the same scope for the DC lifetime. (FullscreenVideoController::draw): Switch to using OwnPtr<HDC> since createCompatibleDCForWindow returns a PassOwnPtr. * WebNodeHighlight.cpp: (WebNodeHighlight::update): Cleaned up leaks from calling GetDC without release. Note that there is a potential leak of hdc that previously existed and still does in an early exit scenario. (This could be easily fixed by using OwnPtr<HDC> but I was trying to keep this patch focused.) * WebView.cpp: (WebView::scrollBackingStore): Typical conversion. (WebView::updateBackingStore): Reduced the scope of windowDC to be right where it is being used. (WebView::performLayeredWindowUpdate): Typical conversion. (WebView::paintIntoBackingStore): Ditto. Source/WebKit2: * Shared/win/ShareableBitmapWin.cpp: (WebKit::ShareableBitmap::windowsContext): Fix incorrect usage of OwnPtr<HDC> which would do a DeleteDC instead of a ReleaseDC. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@105667 268f45cc-cd09-0410-ab3c-d52691b4dbfc
