Skin Framework - CXTPSkinManagerLegacyApiHook::OnHookGetSysColor()

I believe there's a bug in Toolkit for MFC v19.3.0 in CXTPSkinManagerLegacyApiHook::OnHookGetSysColor():

original:

CXTPSkinManagerMetrics* pMetrics = XTPSkinManager()->GetMetrics();

if (NULL != pMetrics && pSkinManager->IsEnabled())

{

crColor = pMetrics->GetColor(nIndex);

bDefaultProcessing = (COLORREF_NULL != crColor);

}

expected:

CXTPSkinManagerMetrics* pMetrics = XTPSkinManager()->GetMetrics();

if (NULL != pMetrics && pSkinManager->IsEnabled())

{

	crColor		   = pMetrics->GetColor(nIndex);

	bDefaultProcessing = (COLORREF_NULL == crColor);

}

So there should be == operator when comparing retrieved color to COLORREF_NULL. Otherwise, themed colors are replaced with the system colors.
