How to test draw page grid lines?

[Regina Henschel]

Hi all,

I have tried a test in sc/ui/uicalc.cxx

But
ScModelObj* pModelObj = createDoc("tdf137083_PageGridInRTLSheet.ods");
does not call SdrPageView::DrawPageViewGrid() at all. And two times 
dispatchCommand(mxComponent, ".uno:GridVisible", {}); does call it neither.

I thought, I could make a kind of screenshot. But when I generate a 
bitmap by
ScDocShell* pDocSh = 
dynamic_cast<ScDocShell*>(SfxObjectShell::GetShellFromComponent(mxComponent)); 

ScGridWindow* pActiveWin = 
dynamic_cast<ScGridWindow*>(pDocSh->GetViewData()->GetActiveWin());
const ::BitmapEx aTempBitmap(pActiveWin->GetBitmapEx(aEmptyPoint, 
pActiveWin->GetOutputSizePixel()));
then I get a entire black bitmap.

Does really nobody have an idea? Otherwise I will commit the patch 
without unit test.

Kind regards
Regina
