Log Message:
-----------
Removing the check for path length; this seems not needed with recent
versions of cairo/pycairo.

Author: mdehoon

Log Message:
-----------
With cairo /pycairo both at version 1.8.8, I'm still seeing crashes with paths
longer than 20000 points or so (tried the gtkcairo backend on Mac OS X). So the
path length check is still needed.
