SVG Essentials – Filters

This is a recreation (for the purpose of tinkering with an implementation in d3.js) of the example from the book SVG Essentials by J. David Eisenberg.

The <feColorMatrix> element allows to change color values in a following way.

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	# The five-step process is outlined here:

	# Matt Swanson wrote a blog post translating the above steps into actual API calls:
	# http://swanson.github.com/blog/2011/07/23/digging-around-the-github-api-take-2.html

	# I was not able to find sample code for actually doing this in Ruby,
	# either via the HTTP API or any of the gems that wrap the API.
	# So in the hopes it will help others, here is a simple function to
