From: Kevin Rogovin <kevin.rogo...@intel.com>
Define the application interface to BatchbufferLogger. The
BatchbufferLogger needs from the application when a GL/GLES
API call is issues and returns. It will use this information
to correctly correlate batchbuffer additions to GL/GLES API
calls.
In addition, because the BatchbufferLogger will be intercepting
drmIoctl, an application does NOT link against it. Instead, one
needs to LD_PRELOAD the .so.
