experiment with srgb: atmosphere looks nicer, but problem with labels. not tested on web and android.

i do not understand, why we need to disable gamma encoding for text. the target buffer should be srgb, so writing without encoding will result in sth that is decoded 1 time too often.

srgba framebuffer support is patchy (not working on android, for webgl you need an extension, which i didn't test). so imo the better option is to manually encode after we are done.
