Thanks a lot Timothy. For some: part of my job might consist in doing this
work  -*for Windows*-  required to actually display the result. Then,
assuming <WebKit-r156532> compiles and runs WebGL content succesfully  *for
Mac  *(probably provided some settings :  'defaults write
WebKitWebGLEnabled -bool YES'  specified from the terminal) would that be a
good approach, according to you, to watch step-by-step what happens across
Mac OS, by using efficient debugger, and report what is missing   -*for
Windows*-   ? To fill the gap...

Do you or anyone assess this analogy to mimic behaviours around OpenGLES2
from Mac OS X to WIN32 (involving Angle in-the-middle ;-) ?

PS: again, sorry for any piece of naivety or groundless indolence in my
analysis: these technical areas turn out to be new to me.
