+ * Vertex fetch/store/convert code. This functionality is used in two places:
+ * 1. Vertex fetch/convert - to grab vertex data from incoming vertex
+ * arrays and convert to format needed by vertex shaders.
+ * 2. Vertex store/emit - to convert simple float[][4] vertex attributes
+ * (which is the organization used throughout the draw/prim pipeline) to
+ * hardware-specific formats and emit into hardware vertex buffers.
