I'm a newbie, and am having a little trouble understanding the documentation for eglChooseConfig.

Can any of the below values be tweaked to get a faster texture upload to screen(draw+swapbuffers+...until by texture actually on the screen), or to restrict opengles to use only one internal buffer?

EGL_CONFIG_CAVEAT
EGL_LEVEL
EGL_NATIVE_RENDERABLE
EGL_MAX_SWAP_INTERVAL
EGL_SURFACE_TYPE

Thanks for your help.
