// 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.

//
