Work Progress - Feb 22 - Feb 26

Research on refactoring Graffiti Grapher app - mainly moving the draw action from the engine to a new SprayCan class, so it can better model the reality.

Challenges:

• The current Graffiti Graphic app is using pCSDT.Presentation.Graphics2D engine, which differs from what I used (and so am more familiar with) previously (pCSDT.Presentation.OpenGL). The Graphics2D engine has no auto drawing the PEngine and PObjects implemented.
• The existing app uses a command execution mechanism different from the Core. We may need to port the command execution mechanism back to the core. But this also means we need to implement repeat() functionality to the core.
