Upgrading the bgfx version

Building bgfx

In the bgfx dir,

..\bx\tools\bin\windows\genie.exe --with-tools --with-shared-lib vs2015
cd .build\projects\vs2015
start bgfx.sln

Change the project configuration to release/x64 and compile. Copy the dll/lib/pdb to trussdeps.

Updating the headers

Edit the c99/bgfx.h header to be like the previous bgfx_truss.c99.h

Updating the defines

Run defines_to_list.py on bgfxdefines.h:

python defines_to_list.py bgfxdefines.h bgfxdefines.lua

Copy the constant names into scripts/devtools/genconstants.t, and edit bootstrap.t to use the real headers on your system by commenting out

terralib.includepath = terralib.includepath .. ";include/fakestd"
```.

Then, run

truss devtools/genconstants.t

Copy the output from trusslog.txt into bgfx_constants.t
