Changes draw command implementation to properly follow
command design pattern. All drawing commands have been
moved to separate inheriting draw commands from renderer.
Other changes:
- New draw methods overloads have been added to pixel renderer.
Now pixel rendering methods are in one class.
- Simplified draw commands naming.
- Changed variable naming in draw commands to be more verbose.
- Changed {x,y} pairs to Points where possible.
