Description
Makes the initialization required to begin drawing on the TCanvas object.
The protected DoBeginScene method is called internally from BeginScene. You should not call DoBeginScene explicitly.
DoBeginScene initializes the pen, brush, and transformation matrix for the current TCanvas object. Override the protected DoBeginScene method to provide another initialization.
