WinDbg stack of OpenGL crash taken from Source panel so with line refs

Thanks Mike, *

Please be gentle, but as I don't clone git and build for Windows locally, I am
working against project builds and downloaded symbol cache. 

But attached is a stack of crash with 6.3.3.2 drawn from the WinDbg source mode
panel which I'd not used before--not sure if I can get more refined to step
through and get vars. Anyhow, crash on this release build matches against the
previous stack for master--but at least now includes the source code lines.

Is that more helpful?  Currently beyond me as to how to read out the
CHECK_GL_ERROR () asserts if that is the next step. 

Stuart
