Fix normals in case of MatrixEffectScale / Shear.
Fix displaying the normal vector.

Update Myanmar flag.

Progress making it possible to apply Vertex Effects only to some Components of a Mesh.

1) Cube: convert it to the latest library. Main difference: objects are rendered better, individual cubits have rounded corners.
2) Examples: some adjustments to MeshJoin & Predeform
3) Library: fix a bug in main_vertex_shader's 'degree' function, which didn't work proprely in case of a vertex which was exactly at the center (i.e. vector PS was zero)

Change 'tag' to a more appropriate name - 'association'.

Introduce 'tags' (soon to be renamed to 'associations') to Mesh and VertexEffect.
A 'tag' is a way to associate a Vertex Effect only to a subgroup of a given Mesh's vertices (more precisely, only to an arbitrary subset of its Components)

Fix licenses :)

Have VERTEX_QUATERNION, VERTEX_ROTATE and VERTEX_SHEAR modify inflate vectors.
Split Vertex attribute array into two (the one modified by preapply effects and the one not)

Speedup for preapply

First attempt at the MeshBase.apply(VertexEffect) API.
