/* Should the rectangles be randomly positioned/colored/rotated?
*
* It could be good to develop equivalent GL and Cairo tests so we can
* have a sanity check for our Cogl performance.
*
* The color should vary to check that we correctly batch color changes
* The use of alpha should vary so we have a variation of which rectangles
* require blending.
* Should this be a random variation?
* It could be good to experiment with focibly enabling blending for
* rectangles that don't technically need it for the sake of extending
* batching. E.g. if you a long run of interleved rectangles with every
* other rectangle needing blending then it may be worth enabling blending
* for all the rectangles to avoid the state changes.
* The modelview should change between rectangles to check the software
* transform codepath.
* Should we group some rectangles under the same modelview? Potentially
* we could avoid software transform for long runs of rectangles with the
* same modelview.
