Update 0.3.0 - preview 2

Hey,

0.3.0-preview-2 brings just a couple of updates I wanted to publish before the week starts for good.

• New features:
  • additional measurements - per dice - to display more information about dice geometry, e.g. point-to-point distance, face-to-face distance, and others.
  • non-uniform face graphic scaling is now possible.
  • when using a mouse scroll over a slider you can change values in smaller increments by holding a Control button, or in larger increments by holding a Shift button.
  • engraving depth can now be negative - you can use this to create raised numbers.
• Improvements/bugfixes
  • PNG tracer is slightly better now.
    • PNG tracer now scales the input image uniformly, taking the traced geometry into account. This should eliminate an issue with "squished" imported images.
    • I fixed an issue where the last vertex in a loop was discarded, this often resulted in one corner of a loop being "cut".
    • Straight vertical/horizontal lines should result in straight edges without any extra vertices.
      SVGs are still a better option than PNGs though. Please try using SVGs instead of PNGs.
  • "Add new dice" button is now properly placed at the bottom of the panel after loading a scene.
