Load font file in FontConfig when using Pango

[balsamiqMarco]

We need the text rendering capabilities of Pango (i.e. kerning), so we built node-canvas with 'with_pango' set to true. Problem is, that we use a custom TrueType font and it seems that node-canvas doesn't load it properly when using Pango.

The proposed change fixes the font loading step by calling FontConfig API.

Sample code:

var canvas = new Canvas(400,40);
var ctx = canvas.getContext('2d');
var Font = Canvas.Font;

var myFont = new Font('MyFont', '../fonts/pip.ttf');
myFont.addFace('../fonts/pipBold.ttf', 'bold');

// Do not call addFont when using Pango
//ctx.addFont(myFont);

ctx.font = "30px MyFont";
ctx.fillText("kerning enabled AVAVAVA", 2, 32);

Applying your change to src/FontFace.cc (as well as setting with_pango to 'true' in bindings.gyp) then running node-gyp rebuild seems to work for me. I'm using pango so as to have fallback fonts working.
