PHP Proxy html2canvas ( php 5.0+ )

This script allows you to use html2canvas.js with different servers, ports and protocols (http, https), preventing to occur "tainted" when exporting the <canvas> for image.

###Problem and Solution### When adding an image that belongs to another domain in <canvas> and after that try to export the canvas for a new image, a security error occurs (actually occurs is a security lock), which can return the error:

SecurityError: DOM Exception 18

Error: An attempt was made to break through the security policy of the user agent.
