fsdk_baseform.h:63:19: error: 'CPDFSDK_Widget::GetLayoutOrder' hides overloaded virtual function [-Werror,-Woverloaded-virtual]
virtual int GetLayoutOrder() {return 2;}

fsdk_baseannot.h:70:18: note: hidden overloaded virtual function 'CPDFSDK_Annot::GetLayoutOrder' declared here: different qualifiers (const vs none)
virtual int GetLayoutOrder() const { return 5; }

On Windows, I believe MSVS treats these as override since it's such a common and
easy mistake, but clang and gcc do what the standard specifies. Add a "const" to
the function in the subclass so that this is actually an override, as intended.
