[Mesa-dev] Implement GLX_EXT_buffer_age for DRI2

2015-01-19 Thread Chris Wilson
In order to suport GLX_EXT_buffer_age in DRI2, we need to pass back the last swap buffer count that the back buffer was defined for. For simplicity, we can reuse an existing field in the DRI2GetBuffers reply that is not used by current drivers, the flags. Since we change the interpretation of this
