- Add love.graphics.setDepthMode(testcomparison, enablewrites). - Add love.graphics.setMeshCullMode. - Add love.graphics.setFrontFaceWinding. Depth testing and depth writes require a depth buffer to work. The mesh cull mode controls whether front/back faces of a mesh are culled. The front face winding determines whether a clockwise or counterclockwise-oriented face in a mesh is considered front facing. --HG-- branch : minor
