microprofile embeds non-free code

[Tachi107]

Hi, microprofile currently contains some non-free JavaScript code embedded in src/microprofile*.html, specifically the HSL to/from RGB functions:

microprofile/src/microprofile.html

Lines 103 to 158 in b20a06d

	function ConvertRgbToHsl(hexTripletColor) //from https://gist.github.com/mjackson/5311256
	{
	var color = hexTripletColor;
	color = color.substring(1);
	color = parseInt(color, 16);
	var r = ((color >> 16) % 256)/255.0;
	var g = ((color >> 8) % 256)/255.0;
	var b = ((color >> 0) % 256)/255.0;
	var max = Math.max(r, g, b), min = Math.min(r, g, b);
	var h, s, l = (max + min) / 2;
	if (max == min) {
	h = s = 0; // achromatic
	}
	else
	{
	var d = max - min;
	s = l > 0.5 ? d / (2 - max - min) : d / (max + min);
	switch (max)
	{
	case r: h = (g - b) / d + (g < b ? 6 : 0); break;
	case g: h = (b - r) / d + 2; break;
	case b: h = (r - g) / d + 4; break;
	}
	h /= 6;
	}
	return [ h, s, l ];
	}
	function ConvertHslToColor(h, s, l) //from https://gist.github.com/mjackson/5311256
	{
	var r, g, b;
	if (s == 0)
	{
	r = g = b = l; // achromatic
	}
	else
	{
	function hue2rgb(p, q, t)
	{
	if (t < 0) t += 1;
	if (t > 1) t -= 1;
	if (t < 1/6) return p + (q - p) * 6 * t;
	if (t < 1/2) return q;
	if (t < 2/3) return p + (q - p) * (2/3 - t) * 6;
	return p;
	}
	var q = l < 0.5 ? l * (1 + s) : l + s - l * s;
	var p = 2 * l - q;
	r = hue2rgb(p, q, h + 1/3);
	g = hue2rgb(p, q, h);
	b = hue2rgb(p, q, h - 1/3);
	}
	var color = ((r*255)<<16) | ((g*255)<<8) | (b*255);
	return '#' + ("000000" + color.toString(16)).slice(-6);
	}

The code from https://gist.github.com/mjackson/5311256 is not licensed, meaning that it cannot be used for any purpose; on the Gist thread, people asked multiple times for a license, but the author never did so.

On that same thread, user @vahidk linked to an alternative implementation free to use for any purpose: https://gist.github.com/mjackson/5311256?permalink_comment_id=2710361#gistcomment-2710361. I'd suggest using that instead.
