// Description:
// This test application is used to test how the scaling works with CFbsBitGc drawing methods.
// TDrawComposite template class is used for the testing. When instantiated, it expects two
// template arguments - TDrawFunctor and TDrawParam:
// 1. TDrawFunctor class. It represents the "functor/function object" pattern and 
// must implement  "void operator()(CFbsBitGc* aGraphicsContext, TDrawParam* aPrm)" method.
// 2. TDrawParam class. This is a template argument for 
// "void TDrawFunctor::operator()(CFbsBitGc* aGraphicsContext, TDrawParam* aPrm)" method.
// If the overloaded "()" operator does not need a parameter, TEmpty class can be used as 
// a template parameter.
// When you instantiate TDrawComposite template class and call TDrawComposite::Draw() method,
// it will perform all pre- and post- drawing steps, calling 
// "void TDrawFunctor::operator()(CFbsBitGc* aGraphicsContext, TDrawParam* aPrm)" 
// at the right time.
// If you want to do the test step by step, set "aCallGetch" parameter of TDrawComposite's
// constructor to ETrue, when using it.
//
