Description:
------------
may be create a method to insure a 'range' value for RGB values like this ; also, lighter() and darker methods are more usable with this specifications.

this _range() method could be used in many method from Image_Color class.

function lighter($color, $degree = 10){
for ( $x = 0; $x < 3; $x++ )
$color[$x] = $this->_range($color[$x]+$degree, 0, 255);

return $color;
}

function darker($color, $degree = -10){
return $this->lighter($color, -$degree);
}

function _range($val, $min, $max){
if($val < $min)
return $min;
if($val > $max)
return $max;
return $val;
}

first off, sorry this go ignored for so long. i've just taken over the package. i like the idea of having separate lighter darker methods. i'm going to commit a couple of bug fixes and get a release out and then look at adding some features like this.
