Made parsing and triangulation of glyphs more robust
- added AxisAlignedBoundingBox.as
- Contour.as now stores an axis aligned bounding box.
- Contour.as now stores a value indicating whether it's vertices are clockwise or counter-clockwise. This indicates whether the contour is a "hole" or not.
- Contour.as now contains the "hole" contours it encloses.
- "hole" contours are ordered depending on the angle of their center to the first vertex of the parent contour.
