Not sure. I need to do some benchmarking, and then more research into if the API can cover everything we want it to do. (which of course means figuring it out). So far I think the API I proposed will help with the Groups we have, and will also help with people who don't care about dirty rects.

It's not really much code... as you can see Leif has already done something like it... it's just a for loop around blit basically.

If someone who just knows python wants to help, they could begin writing unit tests for it in test/surface_test.py

My pygame things are basically these at the moment. If anyone wants to do the blits() API, that's fine too!

* keep improving https://pygame.org/wiki/GettingStarted , gather and file usability bugs with pip, python, pygame...

* help finalise github move decision/move.

* blits

* cython sprites.*Group

* SDL2 stuff

cheers,

I think that special_flags could be shared for all the blits in the

for each.

Yeah, I think you may be right. When I've used it (for particles as an example) it was for everything in a Group. I searched through some code online and found a few uses where it was used in Sprites. But then all of those Sprites were rendered the same. There's some sort of nice symmetry by using the same arguments with blit, and blits however.
