[ Note: These APIs have changed significantly. ] - MeshData and GLMeshItem now operate on numpy arrays instead of lists. - MeshData can handle per-vertex and per-triangle color information Added GLSurfacePlotItem class based on new GLMeshItem GLGraphicsItem now has per-item support for customizing GL state (setGLOptions method) Added several new shader programs Added new examples: GLIsosurface GLSurfacePlot GLshaders
