[PEPr] Comment on Images::Image_CAPTCHA

Jason Lotito (http://pear.php.net/user/jasonlotito) has commented on the proposal for Images::Image_CAPTCHA. Comment: "I have also experimented with other effects like color gradients." Look at using Image_Color::getRange() for color gradients, as well as being able to determine which color you should use for text against a certain background color with Image_Color::getTextColor(). I can also look into providing Image_Color with support for color blind protection, so you don't end up mixing colors that would be a problem for color blind people.
