> Patch by Kondapally Kalyan <kalyan.kondapally@intel.com>; on 2013-03-21
> Reviewed by Kenneth Rohde Christiansen.
> 
> Covered by existing WebGL tests.
> 
> This is in preparation to add transport surface support for GLES2.
> This patch makes it easy to share the core logic of using
> Transport Surface and client on GLX and GLES2 backends without
> any code duplication.

> As GraphicsSurface is deleted on resize, added logic to ensure that
> current buffer is not deleted before having the shared buffer
> with correct size. This would avoid any flashing during resize.
