Ember v1.0.2

• Ember's springs step in pieces no longer than a 60th of a second. At the card's 24 fps tick the old step was
  unstable: a pixel of error rang up until Ember flew off the island (or the island panicked), and the instability
  drove it into bursts of 60 fps frames.
• A missing glyph's fallback font tries fontconfig's candidates until one parses and has it, so Chinese, Japanese
  and Korean text no longer draws as boxes where the first candidate is a .ttc Ember can't read.
