Hi;
Maybe something went wrong since patches 4,6 are missing from this series?
Functionally at least propagating mutableRenderBuffer boolean from
driver to driCreateConfigs is missing.

Despite the KHR, Android is the only OS that uses this extension, as far
as I know. Essentially, it allows the app to toggle
front-buffer/back-buffer rendering using EGL.
Android requires this extension if the device advertises support for
virtual reality. No Chrome OS device yet supports Android's VR software
requirements, though, and VR is not why I implemented this.
This extension enables handwriting and drawing apps on Chrome and
Android devices to achieve very low latency between touch input
and display response.
Please don't bash me for this oddly-specified Android extension.
I didn't create it. I'm just writing the code that Android requires.
* Patch 3 defines a pair of new DRI extensions,
DRI_MutableRenderBuffer{Driver,Loader}.
* Patches 1-5 add the generic code for the DRI and EGL extensions.
* Patch 6 implements DRI_MutableRenderBufferLoader for Android EGL.
* Patch 7 implements DRI_MutableRenderBufferDriver for i965.
