Minor fixes and optimizations.
- Fixed a bug where Contour.as did not find the last closest point when connecting two paths, resulting in problems with the EarClippingTriangulator.as.
- EarClippingTriangulator.as now accepts triangles with no area, preventing infinite loops in some edge cases.
- BatchedGlyphRenderer now sets the length of the vertex and index data vectors instead of pushing the data.
- Implemented changes in SingleGlyphRenderer.as to adapt it to the current structure.
