#649 TUIFace::Paint crashes for icons

[Vidar Hasfjord]

TUIFace::Paint (TDC&, const TPoint&...) calls Bm->Size() for case SourceType == sIcon, in which case Bm is nullptr (see constructor TUIFace::TUIFace (const TRect&, const TIcon&...); since [r3548], Bm is initialised to nullptr, and before then, it was left uninitialised).

This is issue has been fixed in Owlet [r8846].

Resolution: The code now calls TIcon::GetInfo to retrieve icon size.
