We might want to use QSGVertexColorMaterial to improve the "batchability"
as this material does not depend on the specific colors. It could even be
batched with QskBoxNodes, that are usually using QSGVertexColorMaterial as well.
However we would have to store the color information for each vertex.
For the moment we prefer less memory over better "batchability".
