If you think about using OpenGL ES Extension glDrawTexOES for your sprite engine

This took me an embarassingly long time to find out:

If you’re looking for an example on how to use it, here you go:

It doesn’t work in the simulator, in a very silent way, i.e. I got no warning, no error, nothing, just no texture was drawn.

Also:

• No Rotation. Apparently, it does support scaling, I didn’t try it though.
• No portability to desktop OpenGL, extension only seems to be present in OpenGL ES.

So it’s not an option for me, it would have been a nice way to increase drawing performance though I guess.
