Description

Issue or Feature

I've been trying to register a font but whenever I use it I get

Pango-WARNING **: couldn't load font "Avenir Not-Rotated 48px", falling back to "Sans Not-Rotated 48px", expect ugly output.

Steps to Reproduce

var Canvas = require('canvas');
Canvas.registerFont(path.join(__dirname, "fonts", "Avenir.ttf"), { family: "AvenirBook"});
var canvas = Canvas.createCanvas(200, 200);
var ctx = canvas.getContext('2d');
  ctx.font = '48px "AvenirBook"';
ctx.fillText('hello', 50, 50);
// etc.

Avenir font: http://summerfieldmattress.com/skin/frontend/default/craigs/fonts/avenir%20fonts/avenir.ttf

Research direction
Investigate why registerFont fails to load the Avenir font. Check if the font file is valid and if the family name matches. Review Pango font configuration and previous comments in the issue for any hints. Also verify the file path and try a simpler font to isolate the issue.
