Custom monotone coloring
Hey, awesome function and plugin.
I found myself in the situation in wich I had to convert a image to a monotone other than black and white. it wasn't hard tweaking your code to fit my needs but thought I'd share.
Simply go to the grayImage function's switch and add a new case, say custom:

case ("custom"):

                var mono =[pos] * 0.34 +[pos + 1] * 0.5 +[pos + 2] * 0.16;
         [pos] = mono+(r*(1- (mono/255)));
         [pos + 1] = mono+(g*(1- (mono/255)));
         [pos + 2] = mono+(b*(1- (mono/255)));
now replace the r, g and b values for the ones with the target color, in my case it was #ff6666, so r = 255, g = 102, b = 102, and voila, you have a mono tone image in your custom color.
