Just noticed that Opengl ES 1.0, 1.1, and probably also 2.0 don't have an accum buffer in Android.
I'm missing out on some neat effects like a simple fireworks display and realistic (and fast) clouds.
Any alternatives to the accum buffer? In particular, at least in the fireworks code, it looks like it's used for blending.
UPDATE: after taking a more careful look at the fireworks code, the accum buffer is used to create the trails.
