There are a number of things we can potentially use this API for, but right now this just provides a foundation to build on. Please read the extensive list of TODO items in cogl-mesh.c for examples. Please refer to the cogl-mesh section in the reference manual for documentation of the API. * tests/conform/Makefile.am * tests/conform/test-conform-main.c * tests/conform/test-mesh-contiguous.c * tests/conform/test-mesh-interleved.c * tests/conform/test-mesh-mutability.c: Privides basic coverage testing for the mesh API.
