SciPy 2010 Call for Papers
==========================
SciPy 2010, the 9th Python in Science Conference, will be held from
June 28th - July 3rd, 2010 in Austin, Texas.
At this conference, novel applications and breakthroughs made in the
pursuit of science using Python are presented. Attended by leading
figures from both academia and industry, it is an excellent
opportunity to experience the cutting edge of scientific software
development.
The conference is preceded by two days of paid tutorials, during which
community experts provide training on several scientific Python
packages.
We invite you to take part by submitting a talk abstract on the
conference website at:
http://conference.scipy.org
Talk/Paper Submission
=====================
We solicit talks and accompanying papers (either formal academic or
magazine-style articles) that discuss topics regarding scientific
computing using Python, including applications, teaching, development
and research. Papers are included in the peer-reviewed conference
proceedings, published online.
Please note that submissions primarily aimed at the promotion of a
commercial product or service will not be considered.
Important dates for authors include:
 * 11 April: Talk abstracts due
 * 20 April: Notification of acceptance
 * 13 June: Papers due
 * 15 August: Publication of proceedings
Further detail will be made available on http://conference.scipy.org

Thanks, committed this. Renamed "useBtn" to simply "button".

Here is a patch for a new feature for the rectangle selector. it allows the user to specify which mouse button or buttons to use for the rectangle selection. Also included in the diff is a one line change to the rectangle_selector example code to demonstrate the use of the feature. 
Thanks,

Yes I tried without path simplification, and I don't get any crashes. If we need to support older versions of cairo / pycairo, I suggest that we have the path length check after checking the version of cairo / pycairo, and that we perform the path length check after path simplification, so we know how many points will actually be drawn.
