 While how the code compiles is interesting, the more interesting part to
me is how widgets are rendered. A widget has an OnPaint event where you
specify what should be drawn in the widgets rectangle. You draw lines,
text, etc. using LCB drawing code. You only draw exactly what you
need. This is much more efficient than the engine rendering a lot of field
objects nested within multiple groups.
