  Forcefed string animation (just have matching number spaces) including unit conversions and colour names (ie background:["rgba(red,0.1)", "blue"]). High resolution timers (animations should be slightly smoother).
  Various fixes including ticker (loading Velocity in a background window) and color handling.
• 1.3: Code cleanup - no breaking changes known.
• 1.2: Custom tweens. Custom easings. "Finish" command.
• 1.0: File name changed to velocity.js. Read VelocityJS.org/#dependencies.

Comparisons

• CSS transitions are meant for simple interface flourishes.
• jQuery's $.animate() is slow and poorly-equipped for motion design.
• Velocity is a fast, feature-rich standalone alternative to jQuery's $.animate().
