[PATCH v6 01/12] Move weston_output EGL state into gles2-renderer.
John Kåre Alsaker
john.kare.alsaker at gmail.com
Tue Nov 13 10:10:18 PST 2012
This introduces callbacks for output creation and destruction for the gles2-renderer. This enables the gles2-renderer to have per-output state. EGL surface creation is now done by the output_create callback and the EGL surface is stored in the new per-output gles2-renderer state. On the first output_create call, the gles2-renderer will setup it's GL context. This is because EGL requires a EGL surface to be able to use the GL context.
