Second, vertex atribute values are independent of shader program, which means they persist across changing of the shader program. This makes code simpler and reduces GL state changes. Note: Credit goes to Samuel for finding this little gem. :-) For the 25920 solid QGraphicsRectItem test case, this gives 10% improvement on desktop and 27% on the SGX.
