On second thought, let's not blame LGI too early. I am really unsure about what
is causing this.

P.S.:
$ time lua -e 'l = require"lgi" ; c = l.cairo ; s = c.ImageSurface("ARGB32", 10,
10) ; r = c.Context(s) ; for s=1, 10000 do r:rectangle(1, 2, 3, 4) end'
real 0m0.178s
user 0m0.164s
sys 0m0.004s
(That means about 16.7 microseconds per call which is not that much, but
obviously slower than C (0.3 microseconds per call, factor 55))
