I'd prefer if all syntactic sugar was kept in rcairo/packages/cairo/lib/cairo.rb
in the same matter that the syntactic sugar for allowing
cr.rgb_color=0.2, 0.3, 0.4 should be handled entirely in ruby land.

The speed hit taken by doing this in ruby should not be a problem, if
it turns out to be a problem, portions of cairo.rb can be ported to c
later when we have full API coverage and an api that can be agreed
upon.
