From 812ed0644f8f8f71ca403f4e5793f0dbc1fcf9b2 Mon Sep 17 00:00:00 2001 From: Dan Stoza Date: Tue, 2 Jun 2015 15:45:22 -0700 Subject: libgui: Add generation numbers to BufferQueue This change allows producers to set a generation number on a BufferQueue. This number will be embedded in any new GraphicBuffers created in that BufferQueue, and attempts to attach buffers which have a different generation number will fail. It also plumbs the setGenerationNumber method through Surface, with the additional effect that any buffers attached to the Surface after setting a new generation number will automatically be updated with the new number (as opposed to failing, as would happen on through IGBP).
