I think withMappedBuffer does not cover all the use cases of mapped PBO - please add mapBuffer, unmapBuffer to the list of module exports.
They come in handy when trying to do concurrent/async texture streaming.
OK, this would really be easy and I have no objections. But I would really like to understand why withMappedBuffer is not sufficient. Could you please post some code snippets plus an explanation? Leaving a buffer mapped without a matching unmapping sounds a bit strange at first, but I am really willing to learn and improve the buffer API. I am thinking about a new version of my OpenGL binding, which supports only OpenGL 3.x features, without any deprecated API entries/constants. This would be much smaller and probably a bit nicer, but at the price of losing backwards compatibility. Buffers play a much more central role in OpenGL 3.x, so supporting common use cases in the binding is really important. Anyway, improving support for OpenGL 2.1 in the current binding is important, too. Cheers, S.
