/*

 * Input assembler needs to be able to decompose adjacency primitives

 * into something that can be understood by the rest of the pipeline.

 * The specs say that the adjacency primitives are *only* visible

 * in the geometry shader, for everything else they need to be

 * decomposed. Which in most of the cases is not an issue, because the

 * geometry shader always decomposes them for us, but without geometry

 * shader we were passing unchanged adjacency primitives to the

 * rest of the pipeline and causing crashes everywhere.

 * If geometry shader is missing and the input primitive is one of

 * the adjacency primitives we use the code from this file to

 * decompose them into something that the rest of the pipeline can

 * understand.
