Adding reverse-connectivity type (ie cells adjacent to a node).
reverting small indentation change that caused test result output to differ
fixing a bug with cell-to-node explicit connectivity.
adding cell-to-node recenter.
adding renderer support for point normals
VTK importer now correctly reports available cell sets.
added ability to query metadata about cell sets belonging to meshes.
Adding some simple window/plot management to EAVL.
adding start of parallel rendering infrastructure
update copyright notices for 2013.
cleanup to help compilation.

Adding first support for bitmap fonts.
This is basically to give us decent quality text rendering across
a wide range of pixel sizes (and easily renderable in 3D)
with no external dependencies in about 100 KB per font.
I also included bitmap conversions of three Liberation 2.0 open source
fonts: mono, sans, and serif.
fixing a few bugs with fonts and prepping for texture fonts.
Adding first cut at opengl texture support.

Add text annotation capability.
Allow fourth style of text annotation.
We now support the following four styles:
 1) in 2D screen space with size in screen space units
 2) fully in 3D space (rotates with data), sized in 3D world units
 3) billboarded in 3D (aligned to the camera), sized in 3D world units
 4) billboarded in 3D (aligned to the camera), sized in screen space units
cleanup of text annotation classes.
adding rotation support to text annotations.
